fn map_out_event<TMap, TNewOut>(self, map: TMap) -> MapOutEvent<Self, TMap>
where Self: Sized, TMap: FnMut(Self::ToBehaviour) -> TNewOut,

Adds a closure that turns the output event into something else.

fn select<TProto2>( self, other: TProto2, ) -> ConnectionHandlerSelect<Self, TProto2>
where Self: Sized,

Creates a new ConnectionHandler that selects either this handler or other by delegating methods calls appropriately.
