Trait Handler 

pub trait Handler:
    Send
    + Sync
    + 'static {
    // Required method
    fn call(&self, request: Request) -> BoxFuture<Response>;
}

Anything that can answer a request.

Implemented for every async fn(Request) -> impl IntoResponse, so an application never names this trait: it just writes a function.

Required Methods

fn call(&self, request: Request) -> BoxFuture<Response>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
