warp is a Rust Web Server Framework. It is a lightning-fast, composable web server framework for Rust designed for both simplicity and performance. It is built on top of `hyper`, giving you solid HTTP/1 and HTTP/2 support with modern, asynchronous capabilities.
# Key Features - **Composable Filters** for routing, parameter extraction, headers, queries, and more - Built-in support for **JSON**, **form data**, **multipart**, **static files**, and **WebSockets** - Compatible with **HTTP/1** and **HTTP/2**, leveraging Rust’s async ecosystem (via `tokio`) :contentReference[oaicite:2]{index=2}
# Example Usage Here’s how easy it is to define a basic endpoint:
use warp::Filter; #[tokio::main] async fn main() { let hello = warp::path!("hello" / String) .map(|name| format!("Hello, {}!", name)); warp::serve(hello) .run(([127, 0, 0, 1], 3030)) .await; }
This creates a route like `/hello/Sean`, responding with `Hello, Sean!` ([Docs.rs][1], [GitHub][2])
# Usage Scenarios
warp is well-suited to:
* Fast development of REST APIs
* Modular endpoint composition
* High-performance async backends
