embedded-io

IO traits for embedded systems.

Rust's std::io traits are not available in no_std targets, mainly because std::io::Error requires allocation. This crate contains replacement equivalent traits, usable in no_std targets.

The only difference with std::io is Error is an associated type. This allows each implementor to return its own error type, while avoiding dyn or Box. This is how errors are handled in embedded-hal.

Async variations of the traits are also available, returning futures using generic associated types. Note this design is significantly different from both futures::io and tokio::io. The result is much more ergonomic, at the expense of requiring nightly.
