EmbeddedEventLoop

public final class EmbeddedEventLoop : EventLoop

An EventLoop that is embedded in the current running context with no external control.

Unlike more complex EventLoops, such as SelectableEventLoop, the EmbeddedEventLoop has no proper eventing mechanism. Instead, reads and writes are fully controlled by the entity that instantiates the EmbeddedEventLoop. This property makes EmbeddedEventLoop of limited use for many application purposes, but highly valuable for testing and other kinds of mocking.

Warning

Unlike SelectableEventLoop, EmbeddedEventLoop is not thread-safe. This is because it is intended to be run in the thread that instantiated it. Users are responsible for ensuring they never call into the EmbeddedEventLoop in an unsynchronized fashion.

execute(_:)
On an EmbeddedEventLoop, execute will simply use scheduleTask with a deadline of now. This means that task will be run the next time you call EmbeddedEventLoop.run.
Declaration
Swift

public func execute(_ task: @escaping () -> Void)
Show on GitHub
run()
Run all tasks that have previously been submitted to this EmbeddedEventLoop, either by calling execute or events that have been enqueued using scheduleTask/scheduleRepeatedTask/scheduleRepeatedAsyncTask and whose deadlines have expired.
