Poem Framework

A program is like a poem, you cannot write a poem without writing it. --- Dijkstra

A full-featured and easy-to-use web framework with the Rust programming language.


  • Both Ease of use and performance.
  • Minimizing the use of generics.
  • Blazing fast and flexible routing.
  • tower::Service and tower::Layer compatibility.
  • Use poem-openapi to write APIs that comply with OAS3 specifications and automatically generate documents.

use poem::{get, handler, listener::TcpListener, web::Path, Route, Server};

fn hello(Path(name): Path<String>) -> String {
    format!("hello: {}", name)

async fn main() -> Result<(), std::io::Error> {
    let app = Route::new().at("/hello/:name", get(hello));

More examples can be found here.
