Trait Implementations§

Source§

impl<S, Req, F, Res> Svc<Req> for MapSvc<S, F, Res>
where S: Svc<Req>, F: FnMut(S::Res) -> Res + Clone,

Source§

type Res = Res

Output type.
Source§

type Fut = MapSvcFut<S, F, Req, Res>

Response future.
Source§

fn exec(self: Pin<&mut Self>, req: Req) -> Self::Fut

Processes request, producing a future that outputs the response type.
Source§

fn poll_ready(self: Pin<&mut Self>, cx: Context<'_>) -> Poll<()>

To be called before exec to signal wether the service is ready to process requests. As such, the check should be inexpensive. Returning Poll::Pending acts as back-pressure. The default implementation unconditionally indicates the service is ready.
