}Expand description
Represents types having payload inside.
This trait is something between DerefMut and BorrowMut — it allows
only one implementation per type (the output type is associated, not
generic), has implementations for all types P such P: Payload, but
has no magic compiler support like DerefMut does nor does it require
any laws about Eq, Ord and Hash as BorrowMut does.
Also the output type is bounded by the Payload trait.
This trait is mostly used to implement payload setters (on both payloads & requests), so you probably won’t find yourself using it directly.
