Function Channel.consumeAll
Attempts to consume all elements currently in the queue.
bool consumeAll
(
ref FixedRingBuffer!(T,buffer_size) dst
);
bool consumeAll
(
ref FixedRingBuffer!(T,buffer_size) dst
) shared;
This function will block if no elements are available. Once at least one
element is available, the contents of dst will be replaced with all
available elements.
If the empty property is or becomes true before data becomes
avaiable, dst will be left untouched and false is returned.
