    Package Overview

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

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

    monix.reactive exposes the Observable pattern:

    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 atomic

    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...).

  • 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()

sealed abstract class ExecutionModel extends Product with Serializable

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.

  3. abstract def nextFrameIndex(current: Int): Int

    Returns the next frame index in the run-loop.

    Returns the next frame index in the run-loop.

    If the returned integer is zero, then the next cycle in the run-loop should execute asynchronously.

  6. abstract val recommendedBatchSize: Int

    Recommended batch size used for breaking synchronous loops in asynchronous batches.

    Recommended batch size used for breaking synchronous loops in asynchronous batches. When streaming value from a producer to a synchronous consumer it's recommended to break the streaming in batches as to not hold the current thread or run-loop indefinitely.

    This is rounded to the next power of 2, because then for applying the modulo operation we can just do:

    val modulus = recommendedBatchSize - 1
// ...
nr = (nr + 1) & modulus

    For the JVM the default value can be adjusted with:

      java -Dmonix.environment.batchSize=2048 \
       ...
