[](https://travis-ci.org/hyperium/hyper)
A Modern HTTP library for Rust.
[Documentation](http://hyperium.github.io/hyper)
## Overview
Hyper is a fast, modern HTTP implementation written in and for Rust. It
is a low-level typesafe abstraction over raw HTTP, providing an elegant
layer over "stringly-typed" HTTP.
Hyper offers both an HTTP/S client and HTTP server which can be used to drive
complex web applications written entirely in Rust.
The documentation is located at [http://hyperium.github.io/hyper](http://hyperium.github.io/hyper).
__WARNING: Hyper is still under active development. The API is still changing
in non-backwards-compatible ways without warning.__
## Example
Hello World Server:
```rust
fn hello(_: Request, res: Response<Fresh>) {
*res.status_mut() = status::Ok;
let mut res = res.start().unwrap();
res.write(b"Hello World!");
res.end().unwrap();
}
fn main() {
let server = Server::http(Ipv4Addr(127, 0, 0, 1), 1337);
server.listen(hello).unwrap();
}
```
Client:
```rust
fn main() {
// Create a client.
let mut client = Client::new();
// Creating an outgoing request.
let mut res = client.get("http://www.gooogle.com/")
// set a header
.header(Connection(vec![Close]))
// let 'er go!
.send();
// Read the Response.
let body = res.read_to_string().unwrap();
println!("Response: {}", res);
}
```
