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
anddiem_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 thePerKeyQueue
to store messages
