# Welcome to `async-std`
`async-std` along with its [supporting libraries][organization] is a library making your life in async programming easier. It provides provide fundamental implementations for downstream libraries and applications alike. The name reflects the approach of this library: it is a 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 an `task` in a model similar to the `thread` module found in the Rust standard lib. But it does not only include io primitives, but also `async/await` compatible versions of primitives like `Mutex`. You can read more about `async-std` in [the overview chapter][overview-std].
