Forces a buffered asynchronous boundary.
Internally it wraps the observer implementation given to subscribeFn
into a
BufferedSubscriber.
Normally Monifu's implementation guarantees that events are not emitted concurrently,
and that the publisher MUST NOT emit the next event without acknowledgement from the consumer
that it may proceed, however for badly behaved publishers, this wrapper provides
the guarantee that the downstream Observer given in subscribe
will not receive
concurrent events.
WARNING: if the buffer created by this operator is unbounded, it can blow up the process if the data source is pushing events faster than what the observer can consume, as it introduces an asynchronous boundary that eliminates the back-pressure requirements of the data source. Unbounded is the default policy, see BufferPolicy for options.

Concatenates the sequence of Observables emitted by the source into one Observable, without any transformation.
You can combine the items emitted by multiple Observables so that they act like a single Observable by using this method.
The difference between concat and merge is
that concat
cares about ordering of emitted items (e.g. all items emitted by the first observable
in the sequence will come before the elements emitted by the second observable), whereas merge
doesn't care about that (elements get emitted as they come). Because of back-pressure applied to observables,
concat is safe to use in all contexts, whereas merge requires buffering.

Takes longest prefix of elements that satisfy the given predicate and returns a new Observable that emits those elements.

Creates the subscription that eventually starts the stream.
Creates the subscription that eventually starts the stream.
This function is "unsafe" to call because it does not protect the calls to the
given Observer implementation in regards to unexpected exceptions that
violate the contract, therefore the given instance must respect its contract
and not throw any exceptions when the observable calls onNext
,
onComplete
and onError
. if it does, then the behavior is undefined.

is an Observer that respects Monifu Rx contract.
While the destination observer is busy, buffers events then send whatever was buffered in one big batch.

While the destination observer is busy, drop the incoming events.

While the destination observer is busy, drop the incoming events.
While the destination observer is busy, drop the incoming events. When the downstream recovers, we can signal a special event meant to inform the downstream observer how many events where dropped.
is a function used to build a message that will be the first event sent after the observer recovers, a function receiving as argument the number of dropped messages and thus can be used to inform the downstream how many messages it missed.
Creates a new Observable from this Observable and another given Observable, by emitting elements combined in pairs.
Creates a new Observable from this Observable and another given Observable, by emitting elements combined in pairs. If one of the Observable emits fewer events than the other, then the rest of the unpaired events are ignored.
An
AsyncSubject
emits the last value (and only the last value) emitted by the source Observable, and only after that source Observable completes.If the source terminates with an error, the
AsyncSubject
will not emit any items to subsequent subscribers, but will simply pass along the error notification from the source Observable.
