futures-rs
A foundational library for zero-cost asynchronous programming in Rust, providing traits, combinators, and utilities.
What is futures-rs?
Futures-rs is a foundational library for asynchronous programming in Rust that provides core abstractions like the Stream trait and utilities such as `join!` and `select!`. It enables developers to write efficient, non-blocking code with zero-cost abstractions, serving as the building block for Rust's async/await ecosystem. The library solves the problem of composing complex asynchronous operations while maintaining high performance and minimal runtime overhead.
Rust developers building asynchronous applications, libraries, or systems that require efficient non-blocking I/O, concurrency, or reactive programming patterns. It's particularly valuable for those working on networked services, embedded systems, or performance-critical applications.
Developers choose futures-rs because it provides the essential foundations for Rust's async ecosystem with zero-cost abstractions, ensuring no runtime performance penalty. Its support for both standard and `#[no_std]` environments, along with expressive combinators, makes it uniquely versatile for everything from embedded systems to high-performance servers.
