Trait Implementations

impl<F, Req, Fut, Res> Svc<Req> for FnSvc<F>

where F: FnMut(Req) -> Fut + Unpin, Fut: Future<Output = Res>,

type Res = Res

Output type.

type Fut = Fut

Response future.

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

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

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.
