Crate

futures

Core async primitives and combinators for Rust.

What it is

The futures crate provides foundational async building blocks: Stream, Sink, AsyncRead, and AsyncWrite traits, and combinators via FutureExt and StreamExt. It also includes in-process channels, locks, and executor utilities used by runtime-agnostic library code.

Why it is commonly used

The foundational async abstraction layer in Rust. Libraries implement against futures' traits to remain runtime-agnostic. Tokio, async-std, and other runtimes interoperate through these common types.
