Receiver[T]
Receives values from a channel. As an Iter, it can be used
with for or next().
Receivers are returned by channel. Once the channel is closed
and drained, next() raises IterStop; a sender error is re-raised after any
buffered values are drained.
Inherits from: std.Iter[T]
Methods
close()
Closes the receiver. This prevents any more values from being sent and wakes up any waiting senders.
