rkt is an async web framework for Rust with a focus on usability, security, extensibility, and speed.
#[macro_use] extern crate rkt;
#[get("/<name>/<age>")]
fn hello(name: &str, age: u8) -> String {
format!("Hello, {} year old named {}!", age, name)
}
#[launch]
fn rocket() -> _ {
rkt::build().mount("/hello", routes![hello])
}Visiting localhost:8000/hello/John/58 will trigger the hello route, returning
Hello, 58 year old named John!. If <age> can't be parsed as a u8, the route
won't be called and a 404 is returned automatically.
rkt is a community-maintained continuation of Rocket, the Rust web framework originally created by Sergio Benitez and the Rocket contributors. We are deeply grateful for their foundational work — rkt would not exist without it. The original project remains available at github.com/rwf2/Rocket.
