struct NIODeadlineRepresents a point in time.
protocol NIOScheduledCallbackHandlerA type that handles callbacks scheduled with EventLoop.scheduleCallback(at:handler:).
protocol Sendablestruct NIOScheduledCallbackAn opaque handle that can be used to cancel a scheduled callback.
init() Initialize a new NIOAsyncTestingEventLoop.

func advanceTime(to deadline: NIODeadline) async Runs the event loop and moves “time” forward to the given point in time, running any scheduled tasks that need to be run.
func execute(_ task: @escaping () -> Void) On an NIOAsyncTestingEventLoop, execute will simply use scheduleTask with a deadline of now. Unlike with the other operations, this will immediately execute, to eliminate a common class of bugs.
func executeInContext<ReturnType>(_ task: @escaping () throws -> ReturnType) async throws -> ReturnType where ReturnType : Sendable Executes the given function in the context of this event loop. This is useful when it’s necessary to be confident that an operation is “blocking” the event loop. As long as you are executing, nothing else can execute in this loop.
func preconditionInEventLoop(file: StaticString, line: UInt) func preconditionNotInEventLoop(file: StaticString, line: UInt) func run() async Run all tasks that have previously been submitted to this NIOAsyncTestingEventLoop, either by calling execute or events that have been enqueued using scheduleTask/scheduleRepeatedTask/scheduleRepeatedAsyncTask and whose deadlines have expired.
