This is the API documentation for the Monix library.

Package Overview

monix.execution exposes lower level primitives for dealing with asynchronous execution:

monix.execution.atomic exposes the Atomic types, as alternative to java.util.concurrent.atomic
monix.execution.cancelables contains several useful Cancelable implementations
monix.execution.schedulers contains several useful Scheduler implementations
monix.execution.rstreams contains helpers for dealing with the Reactive Streams specification
monix.execution.misc provides miscellaneous primitives useful for dealing with concurrency

monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.

monix.reactive exposes the Observable pattern:

monix.reactive.exceptions groups some exceptions thrown by the implementation
monix.reactive.observables groups reusable Observable implementations
monix.reactive.observers groups reusable Observer implementations
monix.reactive.subjects exposes Subject and ConcurrentSubject, which are implementations of hot observables that function both as input and output

monix.types implements type-class shims, to be translated to type-classes provided by libraries such as Cats or Scalaz.

monix.cats is the optional integration with the Cats library, providing translations for the types described in monix.types.

monix.scalaz is the optional integration with the Scalaz library, providing translations for the types described in monix.types.

package cats

Package exposing the Monix integration with the Cats library.

See the library's documentation at: typelevel.org/cats/

To convert Monix type-class instances into Cats types:

import monix.cats._

To convert Cats type-class instances into Monix types:

import monix.cats.reverse._

Do not bring these imports into the same scope as you can experience conflicts if you do:

// Do not do this!

package atomic

A small toolkit of classes that support compare-and-swap semantics for safe mutation of variables.

On top of the JVM, this means dealing with lock-free thread-safe programming. Also works on top of Javascript, with Scala.js, for API compatibility purposes and because it's a useful way to box a value.

The backbone of Atomic references is this method:

def compareAndSet(expect: T, update: T): Boolean

This method atomically sets a variable to the update value if it currently holds the expect value, reporting true on success or false on failure. The classes in this package also contain methods to get and unconditionally set values.

Building a reference is easy with the provided constructor, which will automatically return the most specific type needed (in the following sample, that's an AtomicDouble, inheriting from AtomicNumber[T]):

val atomicNumber = Atomic(12.2)

atomicNumber.incrementAndGet()
// => 13.2

These also provide useful helpers for atomically mutating of values (i.e. transform, transformAndGet, getAndTransform, etc...) or of numbers of any kind (incrementAndGet, getAndAdd, etc...).

package cancelables

Cancelables represent asynchronous units of work or other things scheduled for execution and whose execution can be canceled.

One use-case is the scheduling done by monix.execution.Scheduler, in which the scheduling methods return a Cancelable, allowing the canceling of the scheduling.

Example:

val s = ConcurrentScheduler()
val task = s.scheduleRepeated(10.seconds, 50.seconds, {
  doSomething()
})

// later, cancels the scheduling ...
task.cancel()

sealed abstract class Ack extends Future[Ack] with Serializable
Represents an acknowledgement of processing that a consumer sends back upstream.
Represents an acknowledgement of processing that a consumer sends back upstream. Useful to implement back-pressure.
trait Cancelable extends Serializable
Represents a one-time idempotent action that can be used to cancel async computations, or to release resources that active data sources are holding.
Represents a one-time idempotent action that can be used to cancel async computations, or to release resources that active data sources are holding.
It is equivalent to java.io.Closeable, but without the I/O focus, or to IDisposable in Microsoft .NET, or to akka.actor.Cancellable.
trait CancelableFuture [+T] extends Future[T] with Cancelable
Represents an asynchronous computation that can be canceled as long as it isn't complete.
sealed abstract class ExecutionModel extends Product with Serializable
Specification for run-loops, imposed by the Scheduler.
Specification for run-loops, imposed by the Scheduler.
When executing tasks, a run-loop can always execute tasks asynchronously (by forking logical threads), or it can always execute them synchronously (same thread and call-stack, by using an internal trampoline), or it can do a mixed mode that executes tasks in batches before forking.
The specification is considered a recommendation for how run loops should behave, but ultimately it's up to the client to choose the best execution model. This can be related to recursive loops or to events pushed into consumers.
trait Listener [-A] extends Serializable
A simple listener interface, to be used in observer pattern implementations or for specifying asynchronous callbacks.
A simple listener interface, to be used in observer pattern implementations or for specifying asynchronous callbacks.
This interface does not provide any usage contract or assumptions on how the onValue(a) function gets called.
It's a replacement for Function1[A,Unit] but it does not inherit from it, precisely because we want to attach Listener semantics to types that cannot be Function1[A,Unit].
In particular monix.eval.Callback is a supertype of Listener, even though Callback is a Try[T] => Unit.
class Macros extends InlineMacros with HygieneUtilMacros
Various implementations for AckExtensions and Scheduler.
Various implementations for AckExtensions and Scheduler.

trait Scheduler extends ExecutionContext with UncaughtExceptionReporter with Executor
A Scheduler is an scala.concurrent.ExecutionContext that additionally can schedule the execution of units of work to run with a delay or periodically.

trait UncaughtExceptionReporter extends Serializable
An exception reporter is a function that logs an uncaught error.
An exception reporter is a function that logs an uncaught error.
Usually taken as an implicit when executing computations that could fail, but that must not blow up the call-stack, like asynchronous tasks.
A default implicit is provided that simply logs the error on STDERR.
