EventHandler::RemoveHandlerEvent::Wrapper
Overview
Meta event, emitted whenever a handler is removed from any event, including itself.
A Wrapper is implicitly created for each handler on every on(), and
besides the handler itself carries the subscription args (once?, async?,
at) — giving listeners on this meta event full insight into the handler.
