Safety

This crate uses #![forbid(unsafe_code)] to ensure everything is implemented in 100% Safe Rust.

Example

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

[handler]

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

[tokio::main]

async fn main() -> Result<(), std::io::Error> { let app = Route::new().at("/hello/:name", get(hello)); let listener = TcpListener::bind("127.0.0.1:3000"); let server = Server::new(listener).await?; server.run(app).await } ```
