SinkType

protocol SinkType

Instances of conforming types are effectively functions with the signature (Element) -> Void.

Useful mainly when the optimizer's ability to specialize generics outstrips its ability to specialize ordinary closures. For example, you may find that instead of:

func f(g: (X)->Void) { ... g(a) ...}

the following generates better code:

func f<T: Sink where T.Element == X>(g: T) { ... g.put(a) ...}
