A fast and correct HTTP implementation for Rust.

Get started by looking over the guides.

Hyper is a relatively low-level library, if you are looking for simple high-level HTTP client, then you may wish to consider reqwest, which is built on top of this library.


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. However, this mostly now around the instability of Future and async. The rest of the API is rather stable now. You can also see the issues in the upcoming milestones.


To get involved, take a look at CONTRIBUTING.

There are two main avenues for real-time chatting about hyper: a Gitter room and irc.mozilla.org/hyper. They are mirrored, so choose whichever format you prefer.
