Bus provides a lock-free, bounded, single-producer, multi-consumer, broadcast channel.
It uses a circular buffer and atomic instructions to implement a lock-free single-producer,
multi-consumer channel. The interface is similar to that of the
except that multiple consumers (readers of the channel) can be produced, whereas only a single
sender can exist. Furthermore, in contrast to most multi-consumer FIFO queues, bus is
broadcast; every send goes to every consumer.
I haven't seen this particular implementation in literature (some extra bookkeeping is necessary to allow multiple consumers), but a lot of related reading can be found in Ross Bencina's blog post "Some notes on lock-free and wait-free algorithms".
See the documentation for usage examples.
