embedded-io-adapters

This project is developed and maintained by the HAL team.

Adapters between the embedded-io and embedded-io-async traits and other IO traits.

The adapters are structs that wrap an I/O stream and implement another family of I/O traits based on the wrapped streams. This allows "converting" from an embedded_io::Read to a std::io::Read or vice versa, for example.

There are no separate adapters for Read/ReadBuf/Write traits. Instead, a single adapter implements the right traits based on what the inner type implements. This allows using these adapters when using combinations of traits, like Read+Write.

Supported traits

For embedded-io:

• std::io traits. Needs the std feature.

For embedded-io-async:

• futures 0.3 traits. Needs the futures-03 feature.
• tokio 1.x traits. Needs the tokio-1 feature.

Minimum Supported Rust Version (MSRV)

This crate is guaranteed to compile on stable Rust 1.60 and up. It might compile with older versions but that may change in any new patch release.

See here for details on how the MSRV may be upgraded.

Enabling any of the tokio-* or futures-* Cargo features 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.
