rkyv_rpc

Synopsis

This crate provides useful macros and utilities for working with rkyv objects in a networked environment, such as RPC commands. It helps to ensure that RPC commands and other data are cross-endian and backwards compatible.

Unlike #[derive(rkyv::Archive)], enums created by this implementation use a custom enum discriminator for which the bytes are mirrored, resulting in the same representation regardless of endianness. Furthermore, this allows for discriminators larger than 1 byte, allowing one to space out custom discriminator values to allow for older software to still accept the same data structures while gracefully failing to recognize newer discriminants.

A framed codec is also provided for safely reading and writing binary streams of rkyv objects.

Cargo Features

• codec (default) - Enables the Encoder/Decoder implementations to write/read rkyv objects to byte buffers and AsyncWrite/AsyncRead streams via tokio's Framed
• unaligned - Enable unaligned accesses by default for rkyv. This saves an extra clone of the incoming bytes before decoding.
• bitflags - Enable a macro to wrap generation of bitflags to be used safely with rkyv.
