Returned by the apply builder.
Builds an ConcurrentQueue value for F data types that implement
the Concurrent type class.
Builds an ConcurrentQueue value for F data types that implement
the Concurrent type class.
This builder uses the Partially-Applied Type technique.

Builds a limited capacity and back-pressured ConcurrentQueue.
Builds a limited capacity and back-pressured ConcurrentQueue.
is the maximum capacity of the internal buffer; note that due to performance optimizations, the capacity of the internal buffer can get rounded to a power of 2, so the actual capacity may be slightly different than the one specified

this queue is built to work with Concurrent data types
is a ContextShift, needed for triggering async boundaries
for fairness reasons, in case there's a need to back-pressure on

unbounded for building an unbounded queue that can use the entire memory available to the process.
Builds an unlimited ConcurrentQueue that can use the entire memory available to the process.

is an optimization parameter — the underlying implementation may use an internal buffer that uses linked arrays, in which case the "chunk size" represents the size of a chunk; providing it is just a hint, it may or may not be used

UNSAFE PROTOCOL: This is unsafe due to problems that can happen via selecting the wrong ChannelType, so use with care.
UNSAFE BECAUSE IMPURE: this builder violates referential transparency, as the queue keeps internal, shared state. Only use when you know what you're doing, otherwise prefer ConcurrentQueue.withConfig or ConcurrentQueue.bounded.
specifies the BufferCapacity, which can be
either "bounded" (with a maximum capacity), or "unbounded"
(UNSAFE) specifies the concurrency scenario, for fine tuning the performance
