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.

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

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

pub 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.
