- val BATCHING: Flag
The Scheduler supports processing in batches via an internal trampoline.
The Scheduler supports processing in batches via an internal trampoline.
Schedulers that implement the batching behavior will recognize monix.execution.schedulers.TrampolinedRunnable instances (via
instanceOf
checks) and make an effort to execute them on the current thread.This flag is exposed via Scheduler.features.

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomic
types, as alternative tojava.util.concurrent.atomic
monix.catnap exposes pure abstractions built on top of the Cats-Effect type classes:
monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.
monix.reactive exposes the
Observable
pattern:Observable
implementationsmonix.tail exposes Iterant for purely functional pull based streaming:
Batch
andBatchCursor
, the alternatives to Scala'sIterable
andIterator
respectively that we are using within Iterant's encodingYou can control evaluation with type you choose - be it Task, Coeval, cats.effect.IO or your own as long as you provide correct cats-effect or cats typeclass instance.
