## Features

* **Fast**: Both _Ease_ of use and performance.
* **Minimal generalization**: Minimizing the use of generics.
* **Open API**: Use [poem-openapi](https://crates.io/crates/poem-openapi) to write APIs that comply with [OAS3](https://github.com/OAI/OpenAPI-Specification) specifications and automatically generate documents.

## Example

```rust
use poem::{handler, route, web::Path, route::get, Server};

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

#[tokio::main]
async fn main() {
    let app = route().at("/hello/:name", get(hello));
    let server = Server::bind("127.0.0.1:3000").await.unwrap();
    server.run(app).await.unwrap();
}

```
