Struct BoxService Copy item path

A boxed Service + Send trait object.

BoxService turns a service into a trait object, allowing the response future type to be dynamic. This type requires both the service and the response future to be Send.

If you need a boxed Service that implements Clone consider using BoxCloneService.

Dynamically dispatched Service objects allow for erasing the underlying Service type and using the Service instances as opaque handles. This can be useful when the service instance cannot be explicitly named for whatever reason.

§Examples

use futures_util::future::ready;
// Respond to requests using a closure, but closures cannot be named...
let svc = service_fn(|mut request: String| {
    request.push_str(" response");
    ready(Ok(request))
});

let service: BoxService<String, String, ()> = BoxService::new(svc);
}
