fn from_err<E>(self) -> FromErrNewService<Self, E> where
    Self: Sized,
    E: From<Self::Error>, 

NewService that create service to map this service's error and new service's init error to any error implementing From for this services Error`.

    Self: Sized,
    F: IntoNewService<B>,
    B: NewService<Config = Self::Config, Request = Result<Self::Response, Self::Error>, Error = Self::Error, InitError = Self::InitError>,
