final class CacheUntilConnectSubscriber[-A] extends Subscriber[A]
Wraps an underlying
Subscriber into an implementation that caches
all events until the call to connect()
happens. After being connected,
the buffer is drained into the underlying
observer, after which all
subsequent events are pushed directly.

Connects the underling observer to the upstream publisher.
Connects the underling observer to the upstream publisher.
Until this call happens, the underlying observer will not receive any events. Instead all incoming events are cached. And after
connect
the cached events will be fed in the underlying subscriber and afterwards we connect the underlying subscriber directly to the upstream source.This function should be idempotent. Calling it multiple times should have the same effect as calling it once.

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.
