• Building an HTTP service by combining the primitive components
• Type-safe routing without (unstable) procedural macros

    let endpoint = path!(@get / "greeting" / String)
        .map(|name: String| {
            format!("Hello, {}!\n", name)
        });

    finchers::server::start(endpoint)
        .serve("127.0.0.1:4000")
