# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## 0.6.1 - 2023-10-22
- Make `SliceWriteError` publicly available.
## 0.6.0 - 2023-10-02
- Prohibit `Write::write` implementations returning `Ok(0)` unless there is no
data to write; consequently remove `WriteAllError` and the `WriteAllError`
variant of `WriteFmtError`. Update the `&mut [u8]` impl to possibly return
a new `SliceWriteError` if the slice is full instead of `Ok(0)`.
- Add `WriteZero` variant to `ErrorKind` for implementations that previously
may have returned `Ok(0)` to indicate no further data could be written.
- `Write::write_all` now panics if the `write()` implementation returns `Ok(0)`.
## 0.5.0 - 2023-08-06
- Add `ReadReady`, `WriteReady` traits. They allow peeking whether the I/O handle is ready to read/write, so they allow using the traits in a non-blocking way.
- Add variants to `ErrorKind` mirroring `std::io::ErrorKind`.
- Add `From` impls to convert between `ErrorKind` and `std::io::ErrorKind`.
- Moved `embedded_io::blocking` to the crate root.
- Split async traits to the `embedded-io-async` crate.
- Split trait adapters to the `embedded-io-adapters` crate.
- Add `std::error` impls for `ReadExactError` & `WriteAllError`.
- Rename trait `Io` to `ErrorType`, for consistency with `embedded-hal`.
- Added optional `defmt` 0.3 support.
## 0.4.0 - 2022-11-25
- Switch all traits to use [`async_fn_in_trait`](https://blog.rust-lang.org/inside-rust/2022/11/17/async-fn-in-trait-nightly.html) (AFIT). Requires `nightly-2022-11-22` or newer.
## 0.3.1 - 2022-10-26
- Fix compilation on recent nightlies (#5)
## 0.3.0 - 2022-05-19
- `FromFutures` adapter now requires `futures` Cargo feature. (breaking change)
- Add `FromTokio` adapter.
- Add blanket impls for `&mut T`, `Box<T>`.
- Add impl `Read`, `BufRead` for `&[u8]`
- Add impl `Write` for `&mut [u8]`
- Add impl `Write` for `Vec<u8>`
- impl `std::error::Error` for `ReadExactError`, `WriteFmtError`.
## 0.2.0 - 2022-05-07
- First release
