[−][src]Trait hyper::service::Service
An asynchronous function from Request
to Response
.
Associated Types
type ReqBody: Payload
The Payload
body of the http::Request
.
type ResBody: Payload
The Payload
body of the http::Response
.
type Error: Into<Box<dyn StdError + Send + Sync>>
The error type that can occur within this Service
.
Note: Returning an Error
to a hyper server will cause the connection
to be abruptly aborted. In most cases, it is better to return a Response
with a 4xx or 5xx status code.
type Future: Future<Item = Response<Self::ResBody>, Error = Self::Error>
The Future
returned by this Service
.
Required methods
fn call(&mut self, req: Request<Self::ReqBody>) -> Self::Future
Calls this Service
with a request, returning a Future
of the response.
Provided methods
fn poll_ready(&mut self) -> Poll<(), Self::Error>
Returns Ready
when the service is able to process requests.
The implementation of this method is allowed to return a Ready
even if
the service is not ready to process. In this case, the future returned
from call
will resolve to an error.
