struct _NIOEventLoopFutureIdentifierAn opaque identifier for a specific EventLoopFuture.
@frozen struct StaticStringA string type designed to represent text that is known at compile time.
@frozen struct UIntAn unsigned integer value type.
init() Initialize a new NIOAsyncTestingEventLoop.
var inEventLoop: Bool { get }var now: NIODeadline { get }The current “time” for this event loop. This is an amount in nanoseconds.

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.
@preconcurrency 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.
