Yields a mutable reference to the service when it is ready to accept a request.

👎Deprecated since 0.4.6: please use the
ServiceExt::ready method insteadYields a mutable reference to the service when it is ready to accept a request.

Executes a new future after this service’s future resolves. This does
not alter the behaviour of the
poll_ready method. Read more§fn map_response<F, Response>(self, f: F) -> MapResponse<Self, F>where

Maps this service’s response value to a different value. This does not
alter the behaviour of the
poll_ready method. Read more§fn map_err<F, Error>(self, f: F) -> MapErr<Self, F>where

Maps this service’s error value to a different value. This does not
alter the behaviour of the
poll_ready method. Read more§fn map_result<F, Response, Error>(self, f: F) -> MapResult<Self, F>where

Maps this service’s result type (
Result<Self::Response, Self::Error>)
to a different value, regardless of whether the future succeeds or
fails. Read more§fn map_request<F, NewRequest>(self, f: F) -> MapRequest<Self, F>where
