Abstract Value Members
- abstract def createSubscriber(cb: Callback[Throwable, R], s: Scheduler): (observers.Subscriber.Sync[In], AssignableCancelable)
Builds a new Subscriber that can be subscribed to an Observable for consuming a stream, with a callback that should eventually get called with a materialized result.
Builds a new Subscriber that can be subscribed to an Observable for consuming a stream, with a callback that should eventually get called with a materialized result.
Notes:
- calling the callback must obey the contract for the Callback type
- the given callback should always get called, unless the upstream gets canceled
- the given callback can be called when the subscriber is finished processing, but not necessarily
- if the given callback isn't called after the subscriber is
done processing, then the
Taskreturned by apply loses the ability to cancel the stream, as thatTaskwill complete before the stream is finished

- final def map[R2](f: (R) => R2): Consumer[In, R2]
Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.
Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.
Note that for applying the mapping function an asynchronous boundary is forced, otherwise it could trigger a stack overflow exception. For more efficient mapping of the result, it's probably better to
mapthe resultingTaskon Observable.consumeWith. - final def mapEval[F[_], R2](f: (R) => F[R2])(implicit F: TaskLike[F]): Consumer[In, R2]
Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.
Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.
The mapping function returns results using a generic
F[_]data type that must implement thecats.effect.Effecttype class. Examples of such classes arecats.effect.IOand monix.eval.Task, thus being able to do asynchronous processing.See mapTask for the version that's specialized on

Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.
The mapping function returns a Task that can be used to process results asynchronously.
Note that for applying the mapping function an asynchronous boundary is forced, otherwise it could trigger a stack overflow exception. For more efficient mapping of the result, it's probably better to

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomictypes, as alternative tojava.util.concurrent.atomicmonix.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
Observablepattern:Observableimplementationsmonix.tail exposes Iterant for purely functional pull based streaming:
BatchandBatchCursor, the alternatives to Scala'sIterableandIteratorrespectively 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.
