makeFailedFuture(_:file:line:)

Other members in extension

Instance members

• var executor: any SerialExecutor
• func any() -> EventLoop

  An EventLoop forms a singular EventLoopGroup, returning itself as ‘any’ EventLoop.

• func assertInEventLoop(file: StaticString, line: UInt)

  Asserts that the current thread is the one tied to this EventLoop. Otherwise, if running in debug mode, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:). Never has any effect in release mode.

• func assertNotInEventLoop(file: StaticString, line: UInt)

  Asserts that the current thread is not the one tied to this EventLoop. Otherwise, if running in debug mode, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:). Never has any effect in release mode.

• func close() throws

  Close this EventLoop.

• func enqueue(consuming ExecutorJob)
• func flatScheduleTask<T>(deadline: NIODeadline, file: StaticString, line: UInt, @escaping () throws -> EventLoopFuture<T>) -> Scheduled<T>

  Schedule a task that is executed by this EventLoop at the given time.

• func flatScheduleTask<T>(in: TimeAmount, file: StaticString, line: UInt, @escaping () throws -> EventLoopFuture<T>) -> Scheduled<T>

  Schedule a task that is executed by this EventLoop after the given amount of time.

• func flatSubmit<T>(@escaping () -> EventLoopFuture<T>) -> EventLoopFuture<T>

  Submit task to be run on this EventLoop.

• func makeCompletedFuture<Success>(Result<Success, Error>) -> EventLoopFuture<Success>

  Creates and returns a new EventLoopFuture that is marked as succeeded or failed with the value held by result.

• func makeCompletedFuture<Success>(withResultOf: () throws -> Success) -> EventLoopFuture<Success>

  Creates and returns a new EventLoopFuture that is marked as succeeded or failed with the value returned by body.

• func makeFailedFuture<T>(Error) -> EventLoopFuture<T>

  Creates and returns a new EventLoopFuture that is already marked as failed. Notifications will be done using this EventLoop as execution NIOThread.

• func makeFutureWithTask<Return>(@escaping () async throws -> Return) -> EventLoopFuture<Return>
• func makeIterator() -> EventLoopIterator

  Returns an EventLoopIterator over this EventLoop.

• func makePromise<T>(of: T.Type, file: StaticString, line: UInt) -> EventLoopPromise<T>

  Creates and returns a new EventLoopPromise that will be notified using this EventLoop as execution NIOThread.

• func makeSucceededFuture<Success>(Success) -> EventLoopFuture<Success>

  Creates and returns a new EventLoopFuture that is already marked as success. Notifications will be done using this EventLoop as execution NIOThread.

• func makeSucceededVoidFuture() -> EventLoopFuture<Void>

  Default implementation of makeSucceededVoidFuture: Return a fresh future (which will allocate).

• func next() -> EventLoop

  An EventLoop forms a singular EventLoopGroup, returning itself as the ‘next’ EventLoop.

• func preconditionInEventLoop(file: StaticString, line: UInt)

  Checks the necessary condition of currently running on the called EventLoop for making forward progress.

• func preconditionNotInEventLoop(file: StaticString, line: UInt)

  Checks the necessary condition of currently not running on the called EventLoop for making forward progress.

• func scheduleRepeatedAsyncTask(initialDelay: TimeAmount, delay: TimeAmount, maximumAllowableJitter: TimeAmount, notifying: EventLoopPromise<Void>?, @escaping (RepeatedTask) -> EventLoopFuture<Void>) -> RepeatedTask

  Schedule a repeated asynchronous task to be executed by the EventLoop with a fixed delay between the end and start of each task.

• func scheduleRepeatedAsyncTask(initialDelay: TimeAmount, delay: TimeAmount, notifying: EventLoopPromise<Void>?, @escaping (RepeatedTask) -> EventLoopFuture<Void>) -> RepeatedTask

  Schedule a repeated asynchronous task to be executed by the EventLoop with a fixed delay between the end and start of each task.

• func scheduleRepeatedTask(initialDelay: TimeAmount, delay: TimeAmount, maximumAllowableJitter: TimeAmount, notifying: EventLoopPromise<Void>?, @escaping (RepeatedTask) throws -> Void) -> RepeatedTask

  Schedule a repeated task to be executed by the EventLoop with a fixed delay between the end and start of each task.

• func scheduleRepeatedTask(initialDelay: TimeAmount, delay: TimeAmount, notifying: EventLoopPromise<Void>?, @escaping (RepeatedTask) throws -> Void) -> RepeatedTask

  Schedule a repeated task to be executed by the EventLoop with a fixed delay between the end and start of each task.

• func submit<T>(@escaping () throws -> T) -> EventLoopFuture<T>

  Submit task to be run on this EventLoop.
