Struct AndThen
pub struct AndThen<S, F> { /* private fields */ }Service returned by the and_then combinator.
Implementations
impl<S, F> AndThen<S, F>
const fn new(inner: S, f: F) -> SelfCreates a new
AndThenservice.fn layer(f: F) -> AndThenLayer<F>Returns a new
Layerthat producesAndThenservices.This is a convenience function that simply calls
AndThenLayer::new.
