Functions

func NewDataQueue

func NewDataQueue() (chan<- interface{}, <-chan interface{})

NewDataQueue creates a pair of channels (a send-only channel and a receive-only channel) which form a queue. Arbitrary data may be sent via the queue. The send-only channel is always available for sending. Data are stored in an internal buffer until they are dequeued by reading from the receive-only channel. If the send-only channel is closed the receive-only channel will be closed after all data are consumed.

func NewEventQueue

func NewEventQueue() (chan<- struct{}, <-chan struct{})

NewEventQueue creates a pair of channels (a send-only channel and a receive-only channel) which form a queue. Events (empty structures) may be sent via the queue. The send-only channel is always available for sending. An internal count of events received but not consumed is maintained. If the send-only channel is closed the receive-only channel will be closed after all events are consumed.
