Struct tower::util::Then[][src]

pub struct Then<S, F> { /* fields omitted */ }
This is supported on crate feature util only.

Service returned by the then combinator.


impl<S, F> Then<S, F>[src]

pub fn new(inner: S, f: F) -> Self[src]

Creates a new Then service.

pub fn layer(f: F) -> ThenLayer<F>[src]

Returns a new Layer that produces Then services.

This is a convenience function that simply calls ThenLayer::new.
