Documentation
Get started by looking over the guides.
Overview
hyper is a fast, safe HTTP implementation written in and for Rust.
hyper offers both an HTTP client and server which can be used to drive complex web applications written entirely in Rust.
hyper makes use of "async IO" (non-blocking sockets) via the Tokio and Futures crates.
Be aware that hyper is still actively evolving towards 1.0, and is likely to experience breaking changes before stabilising. You can also see the 1.0 issue milestone.
