Trait RequestHandler 

Source 
pub trait RequestHandler: Service<HttpRequest, Out = Result<HttpResponse>> { }
Expand description

Trait alias for Service<HttpRequest, Out = Result<HttpResponse>>.

Use RequestHandler as a trait bound to avoid spelling out the full Service<HttpRequest, Out = Result<HttpResponse>> constraint. Any type that implements Service<HttpRequest> with Out = Result<HttpResponse> automatically implements RequestHandler.

§Examples

struct MyHandler<S>(S);

impl<S: RequestHandler> Service<HttpRequest> for MyHandler<S> {
    type Out = Result<HttpResponse>;

    async fn execute(&self, request: HttpRequest) -> Self::Out {
        // Custom processing, then delegate to the inner handler.
        self.0.execute(request).await
    }
}

Dyn Compatibility§

This trait is not dyn compatible.

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