execution
Represents an acknowledgement of processing that a consumer sends back upstream.
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.
Represents an asynchronous computation that can be canceled as long as it isn't complete.
Various implementations for AckExtensions and Scheduler.
Various implementations for AckExtensions and Scheduler.
A Scheduler is an scala.concurrent.ExecutionContext that additionally can
schedule the execution of units of work to run with a delay or periodically.

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.
Utilities for Scala's standard concurrent.Future.
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[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...).
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()
Represents an acknowledgement of processing that a consumer sends back upstream. Useful to implement back-pressure.
