}Expand description
Creates new Service values.
Acts as a service factory. This is useful for cases where new Service
values must be produced. One case is a TCP server listener. The listener
accepts new TCP streams, obtains a new Service value using the
ServiceFactory trait, and uses that new Service value to process inbound
requests on that new TCP stream.
Config is a service factory configuration type.

Required methods
fn new_service(&self, cfg: Cfg) -> Self::Future
fn new_service(&self, cfg: Cfg) -> Self::Future
Create and return a new service value asynchronously.
Provided methods
Map this service’s output to a different type, returning a new service of the resulting type.
Map this service’s error to a different error, returning a new service.
fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, Req, Cfg, F, E> where
F: Fn(Self::InitError) -> E + Clone,
fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, Req, Cfg, F, E> where
F: Fn(Self::InitError) -> E + Clone,
Map this factory’s init error to a different error, returning a new service.
