pub fn layer_fn<T>(f: T) -> LayerFn<T>Expand description
Returns a new LayerFn that implements Layer by calling the
given function.
The Layer::layer method takes a type implementing Service and
returns a different type implementing Service. In many cases, this can
be implemented by a function or a closure. The LayerFn helper allows
writing simple Layer implementations without needing the boilerplate of
a new struct implementing Layer.
