Crate embedded_io
source · [−]Expand description
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.
