[−][src]Trait actix_web::Responder
Trait implemented by types that generate responses for clients.
Types that implement this trait can be used as the return type of a handler.
Associated Types
type Item: Into<AsyncResult<HttpResponse>>
The associated item which can be returned.
type Error: Into<Error>
The associated error which can be returned.
Required methods
fn respond_to<S: 'static>(
self,
req: &HttpRequest<S>
) -> Result<Self::Item, Self::Error>
self,
req: &HttpRequest<S>
) -> Result<Self::Item, Self::Error>
Convert itself to AsyncResult or Error.
