async-std, along with its supporting libraries, is a library making your life in async programming easier. It provides fundamental implementations for downstream libraries and applications alike. The name reflects the approach of this library: it is as closely modeled to the Rust main standard library as possible, replacing all components by async counterparts.
async-std provides an interface to all important primitives: filesystem operations, network operations and concurrency basics like timers. It also exposes a
task in a model similar to the
thread module found in the Rust standard lib. But it does not only include I/O primitives, but also
async/await compatible versions of primitives like
