# `embedded-io-async`

Async IO traits for embedded systems.

This crate contains asynchronous versions of the [`embedded-io`](https://crates.io/crates/embedded-io) traits and shares its scope and design goals.

This project is developed and maintained by the [HAL team](https://github.com/rust-embedded/wg#the-hal-team).

## Optional Cargo features

- **`std`**: Adds `From` impls to convert to/from `std::io` structs, adds `std::error::Error` impls.
- **`alloc`**: Adds blanket impls for `Box`, adds `Write` impl to `Vec`.
- **`defmt-03`**: Derive `defmt::Format` from `defmt` 0.3 for enums and structs.

## Minimum Supported Rust Version (MSRV)

This crate requires Rust nightly newer than `nightly-2022-11-22`, due to requiring support for
`async fn` in traits (AFIT), which is not stable yet. 

Keep in mind Rust nightlies can make backwards-incompatible changes to unstable features
at any time.
