}Expand description
Factory for creating Services.
This is useful for cases where new Services must be produced. One case is a TCP server
listener: a listener accepts new connections, constructs a new Service for each using
the ServiceFactory trait, and uses the new Service to process inbound requests on that
new connection.
Config is a service factory configuration type.
Simple factories may be able to use fn_factory or fn_factory_with_config to
reduce boilerplate.

sourcefn map<F, Res>(self, f: F) -> MapFactory<Self, F, Req, Res, Cfg>where
Self: Sized,
F: Fn(Self::Response) -> Res + Clone,
fn map<F, Res>(self, f: F) -> MapFactory<Self, F, Req, Res, Cfg>where Self: Sized, F: Fn(Self::Response) -> Res + Clone,
Map this service’s output to a different type, returning a new service of the resulting type.
sourcefn map_err<F, E>(self, f: F) -> MapErrFactory<Self, Req, Cfg, F, E>where
Self: Sized,
F: Fn(Self::Error) -> E + Clone,
fn map_err<F, E>(self, f: F) -> MapErrFactory<Self, Req, Cfg, F, E>where Self: Sized, F: Fn(Self::Error) -> E + Clone,
Map this service’s error to a different error, returning a new service.
sourcefn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, Req, Cfg, F, E>where
Self: Sized,
F: Fn(Self::InitError) -> E + Clone,
fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, Req, Cfg, F, E>where Self: Sized, F: Fn(Self::InitError) -> E + Clone,
Map this factory’s init error to a different error, returning a new service.
