warp

A super-easy, composable, web server framework for warp speeds.

The fundamental building block of warp is the Filter: they can be combined and composed to express rich requirements on requests.

Thanks to its Filter system, warp provides these out of the box:

• Path routing and parameter extraction
• Header requirements and extraction
• Query string deserialization
• JSON and Form bodies
• Multipart form data
• Static Files and Directories
• Websockets
• Access logging

Since it builds on top of hyper, you automatically get:

• HTTP/1
• HTTP/2
• Asynchronous
• One of the fastest HTTP implementations
• Tested and correct

Example

Add warp and Tokio to your dependencies:

tokio = { version = "0.2", features = ["macros"] }
warp = "0.2"

And then get started in your main.rs:

use warp::Filter;

#[tokio::main]
async fn main() {
    // GET /hello/warp => 200 OK with body "Hello, warp!"
    let hello = warp::path!("hello" / String)
        .map(|name| format!("Hello, {}!", name));

    warp::serve(hello)
        .run(([127, 0, 0, 1], 3030))
        .await;
}
