v0.43.0 (June 9th, 2022)

New this release:

  • 🎉 (smithy-rs#1381, @alonlud) Add ability to sign a request with all headers, or to change which headers are excluded from signing
  • 🎉 (smithy-rs#1390) Add method ByteStream::into_async_read. This makes it easy to convert ByteStreams into a struct implementing tokio:io::AsyncRead. Available on crate feature rt-tokio only.
  • (smithy-rs#1404, @petrosagg) Add ability to specify a different rust crate name than the one derived from the package name
  • (smithy-rs#1404, @petrosagg) Switch to RustCrypto's implementation of MD5.

Contributors Thank you for your contributions! ❤

v0.42.0 (May 13th, 2022)

Breaking Changes:

  • ⚠🎉 (aws-sdk-rust#494, aws-sdk-rust#519) The aws_smithy_http::byte_stream::bytestream_util::FsBuilder has been updated to allow for easier creation of multi-part requests.

    • FsBuilder::offset is a new method allowing users to specify an offset to start reading a file from.
    • FsBuilder::file_size has been reworked into FsBuilder::length and is now used to specify the amount of data to read.

    With these two methods, it's now simple to create a ByteStream that will read a single "chunk" of a file. The example below demonstrates how you could divide a single File into consecutive chunks to create multiple ByteStreams.

    let example_file_path = Path::new("/example.txt");
let example_file_size = tokio::fs::metadata(&example_file_path).await.unwrap().len();
let chunks = 6;
let chunk_size = file_size / chunks;
let mut byte_streams = Vec::new();

for i in 0..chunks {
    let length = if i == chunks - 1 {
        // If we're on the last chunk, the length to read might be less than a whole chunk.
        // We substract the size of all previous chunks from the total file size to get the
        // size of the final chunk.
        file_size - (i * chunk_size)
    } else {
        chunk_size
    };

    let byte_stream = ByteStream::read_from()
        .path(&file_path)
        .offset(i * chunk_size)
        .length(length)
        .build()
        .await?;

    byte_streams.push(byte_stream);
}

for chunk in byte_streams {
    // Make requests to a service
}

0.41.0 (April 28th, 2022)

Breaking Changes:

  • ⚠ (smithy-rs#1318) Bump MSRV from 1.56.1 to 1.58.1 per our "two versions behind" policy.

New this release:

  • (smithy-rs#1307) Add new trait for HTTP body callbacks. This is the first step to enabling us to implement optional checksum verification of requests and responses.
  • (smithy-rs#1330) Upgrade to Smithy 1.21.0

0.40.2 (April 14th, 2022)

Breaking Changes:

New this release:

Contributors Thank you for your contributions! ❤

0.39.0 (March 17, 2022)

Breaking Changes:

  • ⚠ (aws-sdk-rust#406) aws_types::config::Config has been renamed to aws_types:sdk_config::SdkConfig. This is to better differentiate it from service-specific configs like aws_s3_sdk::Config. If you were creating shared configs with aws_config::load_from_env(), then you don't have to do anything. If you were directly referring to a shared config, update your use statements and struct names.

    Before:

    use aws_types::config::Config;

fn main() {
    let config = Config::builder()
    // config builder methods...
    .build()
    .await;
}

    After:

    use aws_types::SdkConfig;

fn main() {
    let config = SdkConfig::builder()
    // config builder methods...
    .build()
    .await;
}

  • ⚠ (smithy-rs#724) Timeout configuration has been refactored a bit. If you were setting timeouts through environment variables or an AWS profile, then you shouldn't need to change anything. Take note, however, that we don't currently support HTTP connect, read, write, or TLS negotiation timeouts. If you try to set any of those timeouts in your profile or environment, we'll log a warning explaining that those timeouts don't currently do anything.

    If you were using timeouts programmatically, you'll need to update your code. In previous versions, timeout configuration was stored in a single TimeoutConfig struct. In this new version, timeouts have been broken up into several different config structs that are then collected in a timeout::Config struct. As an example, to get the API per-attempt timeout in previous versions you would access it with <your TimeoutConfig>.api_call_attempt_timeout() and in this new version you would access it with <your timeout::Config>.api.call_attempt_timeout(). We also made some unimplemented timeouts inaccessible in order to avoid giving users the impression that setting them had an effect. We plan to re-introduce them once they're made functional in a future update.

New this release:

  • (smithy-rs#1225) DynMiddleware is now cloneable
  • (smithy-rs#1257) HTTP request property bag now contains list of desired HTTP versions to use when making requests. This list is not currently used but will be in an upcoming update.

0.38.0 (Februrary 24, 2022)

Breaking Changes:

  • ⚠ (smithy-rs#1197) aws_smithy_types::retry::RetryKind had its NotRetryable variant split into UnretryableFailure and Unnecessary. If you implement the ClassifyResponse, then successful responses need to return Unnecessary, and failures that shouldn't be retried need to return UnretryableFailure.
  • ⚠ (smithy-rs#1209) aws_smithy_types::primitive::Encoder is now a struct rather than an enum, but its usage remains the same.
  • ⚠ (smithy-rs#1217) ClientBuilder helpers rustls() and native_tls() now return DynConnector and use dynamic dispatch rather than returning their concrete connector type that would allow static dispatch. If static dispatch is desired, then manually construct a connector to give to the builder. For example, for rustls: builder.connector(Adapter::builder().build(aws_smithy_client::conns::https())) (where Adapter is in aws_smithy_client::hyper_ext).

New this release:

  • 🐛 (smithy-rs#1197) Fixed a bug that caused clients to eventually stop retrying. The cross-request retry allowance wasn't being reimbursed upon receiving a successful response, so once this allowance reached zero, no further retries would ever be attempted.

0.37.0 (February 18th, 2022)

Breaking Changes:

  • ⚠ (smithy-rs#1144) Some APIs required that timeout configuration be specified with an aws_smithy_client::timeout::Settings struct while others required an aws_smithy_types::timeout::TimeoutConfig struct. Both were equivalent. Now aws_smithy_types::timeout::TimeoutConfig is used everywhere and aws_smithy_client::timeout::Settings has been removed. Here's how to migrate code your code that depended on timeout::Settings:

    The old way:

    let timeout = timeout::Settings::new()
    .with_connect_timeout(Duration::from_secs(1))
    .with_read_timeout(Duration::from_secs(2));

    The new way:

    // This example is passing values, so they're wrapped in `Option::Some`. You can disable a timeout by passing `None`.
let timeout = TimeoutConfig::new()
    .with_connect_timeout(Some(Duration::from_secs(1)))
    .with_read_timeout(Some(Duration::from_secs(2)));

  • ⚠ (smithy-rs#1085) Moved the following re-exports into a types module for all services:

    • <service>::AggregatedBytes -> <service>::types::AggregatedBytes
    • <service>::Blob -> <service>::types::Blob
    • <service>::ByteStream -> <service>::types::ByteStream
    • <service>::DateTime -> <service>::types::DateTime
    • <service>::SdkError -> <service>::types::SdkError

  • ⚠ (smithy-rs#1085) AggregatedBytes and ByteStream are now only re-exported if the service has streaming operations, and Blob/DateTime are only re-exported if the service uses them.

  • ⚠ (smithy-rs#1130) MSRV increased from 1.54 to 1.56.1 per our 2-behind MSRV policy.

New this release:

  • (smithy-rs#1144) MakeConnectorFn, HttpConnector, and HttpSettings have been moved from aws_config::provider_config to aws_smithy_client::http_connector. This is in preparation for a later update that will change how connectors are created and configured.
  • (smithy-rs#1123) Refactor Document shape parser generation
  • (smithy-rs#1085) The Client and Config re-exports now have their documentation inlined in the service docs

  • ⚠ (smithy-rs#990) Codegen will no longer produce builders and clients with methods that take impl Into<T> except for strings and boxed types.
  • ⚠ (smithy-rs#1003) The signature of aws_smithy_protocol_test::validate_headers was made more flexible but may require adjusting invocations slightly.

New this release:

  • 🎉 (aws-sdk-rust#47, smithy-rs#1006) Add support for paginators! Paginated APIs now include .into_paginator() and (when supported) .into_paginator().items() to enable paginating responses automatically.

v0.33.0 (December 15th, 2021)

Breaking Changes:

  • ⚠ (smithy-rs#930) Runtime crates no longer have default features. You must now specify the features that you want when you add a dependency to your Cargo.toml.

    Upgrade guide

Breaking Changes

  • (aws-smithy-client): Extraneous pub use SdkSuccess removed from aws_smithy_client::hyper_ext. (smithy-rs#855)

v0.29.0-alpha (November 11th, 2021)

Breaking Changes

Several breaking changes around aws_smithy_types::Instant were introduced by smithy-rs#849:

  • aws_smithy_types::Instant from was renamed to DateTime to avoid confusion with the standard library's monotonically non-decreasing Instant type.
  • DateParseError in aws_smithy_types has been renamed to DateTimeParseError to match the type that's being parsed.
  • The chrono-conversions feature and associated functions have been moved to the aws-smithy-types-convert crate.
    • Calls to Instant::from_chrono should be changed to: 
      use aws_smithy_types::DateTime;
use aws_smithy_types_convert::date_time::DateTimeExt;

// For chrono::DateTime<Utc>
let date_time = DateTime::from_chrono_utc(chrono_date_time);
// For chrono::DateTime<FixedOffset>
let date_time = DateTime::from_chrono_offset(chrono_date_time);
    • Calls to instant.to_chrono() should be changed to: 
      use aws_smithy_types_convert::date_time::DateTimeExt;

date_time.to_chrono_utc();
  • Instant::from_system_time and Instant::to_system_time have been changed to From trait implementations.
    • Calls to from_system_time should be changed to: 
      DateTime::from(system_time);
// or
let date_time: DateTime = system_time.into();
    • Calls to to_system_time should be changed to: 
      SystemTime::from(date_time);
// or
let system_time: SystemTime = date_time.into();
  • Several functions in Instant/DateTime were renamed:
    • Instant::from_f64 -> DateTime::from_secs_f64
    • Instant::from_fractional_seconds -> DateTime::from_fractional_secs
    • Instant::from_epoch_seconds -> DateTime::from_secs
    • Instant::from_epoch_millis -> DateTime::from_millis
    • Instant::epoch_fractional_seconds -> DateTime::as_secs_f64
    • Instant::has_nanos -> DateTime::has_subsec_nanos
    • Instant::epoch_seconds -> DateTime::secs
    • Instant::epoch_subsecond_nanos -> DateTime::subsec_nanos
    • Instant::to_epoch_millis -> DateTime::to_millis
  • The DateTime::fmt method is now fallible and fails when a DateTime's value is outside what can be represented by the desired date format.
  • In aws-sigv4, the SigningParams builder's date_time setter was renamed to time and changed to take a std::time::SystemTime instead of a chrono's DateTime<Utc>.

New this week

  • ⚠️ MSRV increased from 1.53.0 to 1.54.0 per our 3-behind MSRV policy.
  • Conversions from aws_smithy_types::DateTime to OffsetDateTime from the time crate are now available from the aws-smithy-types-convert crate. (smithy-rs#849)
  • Fixed links to Usage Examples (smithy-rs#862, @floric)

v0.28.0-alpha (November 11th, 2021)

No changes since last release except for version bumping since older versions of the AWS SDK were failing to compile with the 0.27.0-alpha.2 version chosen for the previous release.

v0.27.0-alpha.2 (November 9th, 2021)

Breaking Changes

  • Members named builder on model structs were renamed to builder_value so that their accessors don't conflict with the existing builder() methods (smithy-rs#842)

  • moduleDescription in smithy-build.json settings is now optional
  • Upgrade to Smithy 1.12
  • hyper::Error(IncompleteMessage) will now be retried (smithy-rs#815)

  • Fix generated docs on unions. (smithy-rs#826)

v0.27 (October 20th, 2021)

Breaking Changes

  • ⚠️ All Smithy runtime crates have been renamed to have an aws- prefix. This may require code changes:
    • Cargo.toml changes:
      • smithy-async -> aws-smithy-async
      • smithy-client -> aws-smithy-client
      • smithy-eventstream -> aws-smithy-eventstream

New this week

  • Filled in missing docs for services in the rustdoc documentation (smithy-rs#779)

v0.26 (October 15th, 2021)

Breaking Changes

  • ⚠️ The rust-codegen plugin now requires a moduleDescription in the smithy-build.json file. This property goes into the generated Cargo.toml file as the package description. (smithy-rs#766)

New this week

New this week

  • 🐛 Re-add missing deserialization operations that were missing because of a typo in HttpBoundProtocolGenerator.kt

v0.25 (October 7th, 2021)

Breaking changes

  • ⚠️ MSRV increased from 1.52.1 to 1.53.0 per our 3-behind MSRV policy.
  • ⚠️ smithy_client::retry::Config field max_retries is renamed to max_attempts
    • This also brings a change to the semantics of the field. In the old version, setting max_retries to 3 would mean that up to 4 requests could occur (1 initial request and 3 retries). In the new version, setting max_attempts to 3 would mean that up to 3 requests could occur (1 initial request and 2 retries).
  • ⚠️ smithy_client::retry::Config::with_max_retries method is renamed to with_max_attempts
  • ⚠️ Several classes in the codegen module were renamed and/or refactored (smithy-rs#735):
    • ProtocolConfig became CodegenContext and moved to software.amazon.smithy.rust.codegen.smithy
    • HttpProtocolGenerator became ProtocolGenerator and was refactored to rely on composition instead of inheritance
    • HttpProtocolTestGenerator became ProtocolTestGenerator
    • Protocol moved into software.amazon.smithy.rust.codegen.smithy.protocols
  • SmithyConnector and DynConnector now return ConnectorError instead of Box<dyn Error>. If you have written a custom connector, it will need to be updated to return the new error type. (#744)
  • The DispatchError variant of SdkError now contains ConnectorError instead of Box<dyn Error> (#744).

New this week

  • 🐛 Fix an issue where smithy-xml may have generated invalid XML (smithy-rs#719)
  • Add RetryConfig struct for configuring retry behavior (smithy-rs#725)
  • 🐛 Fix error when receiving empty event stream messages (smithy-rs#736)

  • 🐛 Fixes naming collision during generation of model shapes that collide with <operationname>Input and <operationname>Output (#699)

v0.22 (September 2nd, 2021)

This release adds support for three commonly requested features:

  • More powerful credential chain
  • Support for constructing multiple clients from the same configuration
  • Support for Transcribe streaming and S3 Select

In addition, this overhauls client configuration which lead to a number of breaking changes. Detailed changes are inline.

Current Credential Provider Support:

  • Environment variables
  • Web Identity Token Credentials
  • Profile file support (partial)
    • Credentials
      • SSO
      • ECS Credential source
      • IMDS credential source
      • Assume role from source profile
      • Static credentials source profile
      • WebTokenIdentity provider
    • Region
  • IMDS
  • ECS

Upgrade Guide

If you use <sdk>::Client::from_env

from_env loaded region & credentials from environment variables only. Default sources have been removed from the generated SDK clients and moved to the aws-config package. Note that the aws-config package default chain adds support for profile file and web identity token profiles.

  1. Add a dependency on aws-config: 
    [dependencies]
aws-config = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha" }
  2. Update your client creation code: 
    // `shared_config` can be used to construct multiple different service clients!
let shared_config = aws_config::load_from_env().await;
// before: <service>::Client::from_env();
let client = <service>::Client::new(&shared_config)

If you used <client>::Config::builder()

Config::build() has been modified to not fallback to a default provider. Instead, use aws-config to load and modify the default chain. Note that when you switch to aws-config, support for profile files and web identity tokens will be added.

  1. Add a dependency on aws-config:

    [dependencies]
aws-config = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha" }

  2. Update your client creation code:

    fn before() {
  let region = aws_types::region::ChainProvider::first_try(<1 provider>).or_default_provider();
  let config = <service>::Config::builder().region(region).build();
  let client = <service>::Client::from_conf(&config);
}

async fn after() {
  use aws_config::meta::region::RegionProviderChain;
  let region_provider = RegionProviderChain::first_try(<1 provider>).or_default_provider();
  // `shared_config` can be used to construct multiple different service clients!
  let shared_config = aws_config::from_env().region(region_provider).load().await;
  let client = <service>::Client::new(&shared_config)
}

If you used aws-auth-providers

All credential providers that were in aws-auth-providers have been moved to aws-config. Unless you have a specific use case for a specific credential provider, you should use the default provider chain:

 let shared_config = aws_config::load_from_env().await;
 let client = <service>::Client::new(&shared_config);

If you maintain your own credential provider

AsyncProvideCredentials has been renamed to ProvideCredentials. The trait has been moved from aws-auth to aws-types. The original ProvideCredentials trait has been removed. The return type has been changed to by a custom future.

For synchronous use cases:

use aws_types::credentials::{ProvideCredentials, future};

#[derive(Debug)]
struct CustomCreds;
impl ProvideCredentials for CustomCreds {
  fn provide_credentials<'a>(&'a self) -> future::ProvideCredentials<'a>
    where
            Self: 'a,
  {
    // if your credentials are synchronous, use `::ready`
    // if your credentials are loaded asynchronously, use `::new`
    future::ProvideCredentials::ready(todo!()) // your credentials go here
  }
}

For asynchronous use cases:

use aws_types::credentials::{ProvideCredentials, future, Result};

#[derive(Debug)]
struct CustomAsyncCreds;
impl CustomAsyncCreds {
  async fn load_credentials(&self) -> Result {
    Ok(Credentials::from_keys("my creds...", "secret", None))
  }
}

impl ProvideCredentials for CustomCreds {
  fn provide_credentials<'a>(&'a self) -> future::ProvideCredentials<'a>
    where
            Self: 'a,
  {
    future::ProvideCredentials::new(self.load_credentials())
  }
}

Changes

Breaking Changes

  • Credential providers from aws-auth-providers have been moved to aws-config (#678)

  • AsyncProvideCredentials has been renamed to ProvideCredentials. The original non-async provide credentials has been removed. See the migration guide above.

  • <sevicename>::from_env() has been removed (#675). A drop-in replacement is available:

    1. Add a dependency on aws-config: 
      [dependencies]
aws-config = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha" }
    2. Update your client creation code: 
      let client = <service>>::Client::new(&aws_config::load_from_env().await)

  • ProvideRegion has been moved to aws_config::meta::region::ProvideRegion. (#675)

  • aws_types::region::ChainProvider has been moved to aws_config::meta::region::RegionProviderChain (#675).

  • ProvideRegion is now asynchronous. Code that called provider.region() must be changed to provider.region().await.

  • <awsservice>::Config::builder() will not load a default region. To preserve previous behavior:

    1. Add a dependency on aws-config: 
      [dependencies]
aws-config = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.17-alpha" }
    2. let shared_config = aws_config::load_from_env().await;
let config = <service>::config::Builder::from(&shared_config).<other builder modifications>.build();

  • Request and Response in smithy_http::operation now use SharedPropertyBag instead of Arc<Mutex<PropertyBag>>. Use the acquire and acquire_mut methods to get a reference to the underlying PropertyBag to access properties. (#667)

v0.21 (August 19th, 2021)

New This Week

  • 🎉 Add Chime Identity, Chime Messaging, and Snow Device Management support (#657)
  • 🎉 Add profile file credential provider implementation. This implementation currently does not support credential sources for assume role providers other than environment variables. (#640)
  • 🎉 Add support for WebIdentityToken providers via profile & environment variables. (#654)
  • 🐛 Fix name collision that occurred when a model had both a union and a structure named Result (#643)
  • 🐛 Fix STS Assume Role with WebIdentity & Assume role with SAML to support clients with no credentials provided (#652)
  • Update AWS SDK models (#657)
  • Add initial implementation of a default provider chain. (#650)

  • Remove Bintray/JCenter source from gradle build. (#651)
  • Add experimental dvr module to smithy-client. This will enable easier testing of HTTP traffic. (#640)
  • Update smithy-client to simplify creating HTTP/HTTPS connectors (#650)
  • Add Event Stream support to aws-sigv4 (#648)
  • Add support for the smithy auth trait. This enables authorizations that explicitly disable authorization to work when no credentials have been provided. (#652)

v0.20 (August 10th, 2021)

Breaking changes

  • (#635) The config(), config_mut(), request(), and request_mut() methods on operation::Request have been renamed to properties(), properties_mut(), http(), and http_mut() respectively.

  • (#635) The Response type on Tower middleware has been changed from http::Response<SdkBody> to operation::Response. The HTTP response is still available from the operation::Response using its http() and http_mut() methods.

  • (#635) The ParseHttpResponse trait's parse_unloaded() method now takes an operation::Response rather than an http::Response<SdkBody>.

  • (#626) ParseHttpResponse no longer has a generic argument for the body type, but instead, always uses SdkBody. This may cause compilation failures for you if you are using Smithy generated types to parse JSON or XML without using a client to request data from a service. The fix should be as simple as removing <SdkBody> in the example below:

    Before:

    let output = <Query as ParseHttpResponse<SdkBody>>::parse_loaded(&parser, &response).unwrap();

    After:

    let output = <Query as ParseHttpResponse>::parse_loaded(&parser, &response).unwrap();

New This Week

  • Add AssumeRoleProvider parser implementation. (#632)
  • The closure passed to provide_credentials_fn can now borrow values (#637)
  • Add Sender/Receiver implementations for Event Stream (#639)
  • Bring in the latest AWS models (#630)

v0.19 (August 3rd, 2021)

IoT Data Plane is now available! If you discover it isn't functioning as expected, please let us know!

  • 🎉 Add LazyCachingCredentialsProvider to aws-auth for use with expiring credentials, such as STS AssumeRole. Update STS example to use this new provider (#578, #595)
  • 🐛 Correctly encode HTTP Checksums using base64 instead of hex. Fixes aws-sdk-rust#164. (#615)
  • Update SDK gradle build logic to use gradle properties (#620)
  • Overhaul serialization/deserialization of numeric/boolean types. This resolves issues around serialization of NaN/Infinity and should also reduce the number of allocations required during serialization. (#618)
  • Update SQS example to clarify usage of FIFO vs. standard queues (#622, @trevorrobertsjr)
  • Implement Event Stream frame encoding/decoding (#609, #619)

v0.18.1 (July 27th 2021)

  • Remove timestreamwrite and timestreamquery from the generated services (#613)

v0.18 (July 27th 2021)

Breaking changes

  • test-util has been made an optional dependency and has moved from aws-hyper to smithy-http. If you were relying on aws_hyper::TestConnection, add smithy-client as a dependency and enable the optional test-util feature. This prunes some unnecessary dependencies on roxmltree and serde_json for most users. (#608)

New This Week

  • 🎉 Release all but three remaining AWS services! Glacier, IoT Data Plane and Transcribe streaming will be available in a future release. If you discover that a service isn't functioning as expected please let us know! (#607)
