trait Observer[-A] extends Serializable
The Observer from the Rx pattern is the trio of callbacks that get subscribed to an Observable for receiving events.
The events received must follow the Rx grammar, which is: onNext * (onComplete | onError)?
That means an Observer can receive zero or multiple events, the stream
ending either in one or zero onComplete or onError (just one, not both),
and after onComplete or onError, a well behaved Observable
implementation shouldn't send any more onNext events.

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.
