Crate channel[−][src]
Expand description
Provides an mpsc (multi-producer single-consumer) channel wrapped in an
IntGauge that counts the number of currently
queued items. While there is only one [channel::Receiver], there can be
many [channel::Sender]s, which are also cheap to clone.
This channel differs from our other channel implementation, [channel::diem_channel],
in that it is just a single queue (vs. different queues for different keys)
with backpressure (senders will block if the queue is full instead of evicting
another item in the queue) that only implements FIFO (vs. LIFO or KLAST).
Modules
diem_channel provides an mpsc channel which has two ends diem_channel::Receiver
and diem_channel::Sender similar to existing mpsc data structures.
What makes it different from existing mpsc channels is that we have full control
over how the internal queueing in the channel happens and how we schedule messages
to be sent out from this channel.
Internally, it uses the PerKeyQueue to store messages
