Expand description

An extension trait for `ServiceFactory`s that provides a variety of convenient adapters.

## Provided Methods§

source

#### fn map<F, R>(self, f: F) -> MapServiceFactory<Self, F, Req, R>
where Self: Sized, F: FnMut(Self::Response) -> R + Clone,

Map this service’s output to a different type, returning a new service of the resulting type.

source

#### fn map_err<F, E>(self, f: F) -> MapErrServiceFactory<Self, Req, F, E>
where Self: Sized, F: Fn(Self::Error) -> E + Clone,

Map this service’s error to a different error, returning a new service.

source

#### fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, F, Req, E>
where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

Map this factory’s init error to a different error, returning a new service.

source

#### fn and_then<I, SF1>(self, factory: I) -> AndThenServiceFactory<Self, SF1, Req>
where Self: Sized, Self::Config: Clone, I: IntoServiceFactory<SF1, Self::Response>, SF1: ServiceFactory<Self::Response, Config = Self::Config, Error = Self::Error, InitError = Self::InitError>,

Call another service after call to this one has resolved successfully.
