  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.execution.exceptions groups some exceptions thrown by the implementation

  monix.catnap exposes pure abstractions built on top of the Cats-Effect type classes:

  • monix.catnap.cancelables exposes pure counterparts to the cancelable data types described in monix.execution.cancelables

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

  monix.reactive exposes the Observable pattern:

  • 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.tail exposes Iterant for purely functional pull based streaming:

  • monix.tail.batches describes Batch and BatchCursor, the alternatives to Scala's Iterable and Iterator respectively that we are using within Iterant's encoding

  You 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.

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

  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[A]):

  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...).

  execution

•  package cancelables

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

  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()
