Rocket web framework

Rocket is a web framework for Rust that makes it simple to write fast, type-safe, secure web applications with incredible usability, productivity and performance.

Here's a basic usage example:

#[macro_use] extern crate rocket;

#[get("/")]
fn index() -> &'static str {
    "Hello, world!"
}

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/", routes![index])
}
