fs2.concurrent

Provides mechanisms for balancing the distribution of chunks across multiple streams.

Provides mechanisms for broadcast distribution of elements to multiple streams.

Provides the ability to dequeue chunks of elements from a Queue as streams.

Provides the ability to dequeue individual elements from a Queue.

Provides the ability to dequeue individual chunks from a Queue.

Provides the ability to enqueue elements to a Queue.

Extension of Queue that allows peeking and inspection of the current size.

Like Queue, but allows allows signalling of no further enqueues by enqueueing None. Optimizes dequeue to minimum possible boxing.

A queue of elements. Operations are all nonblocking in their implementations, but may be 'semantically' blocking. For instance, a queue may have a bound on its size, in which case enqueuing may block (be delayed asynchronously) until there is an offsetting dequeue.

Pure holder of a single value of type A that can be read in the effect F.

Pure holder of a single value of type A that can be both read and updated in the effect F.

Asynchronous Topic.

Topic allows you to distribute A published by arbitrary number of publishers to arbitrary number of subscribers.

Topic has built-in back-pressure support implemented as maximum bound (maxQueued) that a subscriber is allowed to enqueue. Once that bound is hit, publishing may semantically block until the lagging subscriber consumes some of its queued elements.

Additionally the subscriber has possibility to terminate whenever size of enqueued elements is over certain size by using subscribeSize.
