chore(deps): bump subxt from 0.27.1 to 0.31.0 in /rust

[dependabot]

Bumps subxt from 0.27.1 to 0.31.0.

Release notes

Sourced from subxt's releases.

v0.31.0

[0.31.0] - 2023-08-02

This is a small release whose primary goal is to bump the versions of scale-encode, scale-decode and scale-value being used, to benefit from recent changes in those crates.

scale-decode changes how compact values are decoded as part of #1103. A compact encoded struct should now be properly decoded into a struct of matching shape (which implements DecodeAsType). This will hopefully resolve issues around structs like Perbill. When decoding the SCALE bytes for such types into scale_value::Value, the Value will now be a composite type wrapping a value, and not just the value.

We've also figured out how to sign extrinsics using browser wallets when a Subxt app is compiled to WASM; see #1067 for more on that!

The key commits:

Added

• Add browser extension signing example (#1067)

Changed

• Bump to latest scale-encode/decode/value and fix test running (#1103)
• Set minimum supported rust-version to 1.70 (#1097)

Fixed

• Tests: support 'substrate-node' too and allow multiple binary paths (#1102)

v0.30.0

[0.30.0] - 2023-07-24

This release beings with it a number of exciting additions. Let's cover a few of the most significant ones:

Light client support (unstable)

This release adds support for light clients using Smoldot, both when compiling native binaries and when compiling to WASM to run in a browser environment. This is unstable for now while we continue testing it and work on making use of the new RPC APIs.

Here's how to use it:

use subxt::{
    client::{LightClient, LightClientBuilder},
    PolkadotConfig
};
use subxt_signer::sr25519::dev;
// Create a light client:
let api = LightClient::<PolkadotConfig>::builder()
// You can also pass a chain spec directly using build, which is preferred:
.build_from_url("ws://127.0.0.1:9944")
.await?;
// Working with the interface is then the same as before:
</tr></table>

[0.30.1] - 2023-07-25

This patch release fixes a small issue whereby using runtime_metadata_url in the Subxt macro would still attempt to download unstable metadata, which can fail at the moment if the chain has not updated to stable V15 metadata yet (which has a couple of changes from the last unstable version). Note that you're generally encouraged to use runtime_metadata_path instead, which does not have this issue.

Fixes

• codegen: Fetch and decode metadata version then fallback (#1092)
