Expand description
Trait for decorating an implementation of the API with common pre/post-handling for all request types.
The ApiDecorator and ApiDispatch traits are similar. Only ApiDispatch
(defined in mod server
) has the req
argument to dispatch
. That
aside, attmpting to combine them into a single trait would result in
circular trait implementations impl ApiDispatch for A: Api
and
impl Api for T: ApiDecorator
.
