Return a succeeded Void future.
func makeSucceededVoidFuture() -> EventLoopFuture<Void> s7NIOCore9EventLoopP23makeSucceededVoidFutureAA0bcG0CyytGyF What are these?4OKCOSemantically, this function is equivalent to calling makeSucceededFuture(()). Contrary to makeSucceededFuture, makeSucceededVoidFuture is a customization point for EventLoops which allows EventLoops to cache a pre-succeeded Void future to prevent superfluous allocations.
import NIOCoreThe core abstractions that make up SwiftNIO.
protocol EventLoop : EventLoopGroupAn EventLoop processes IO / tasks in an endless loop for Channels until it’s closed.
final class EventLoopFuture<Value>Holder for a result that will be provided later.
typealias Void = ()The return type of functions that don’t explicitly specify a return type, that is, an empty tuple ().
var executor: any SerialExecutor { get }Returns a SerialExecutor corresponding to this EventLoop.
var inEventLoop: Bool { get }Returns true if the current NIOThread is the same as the NIOThread that is tied to this EventLoop. false otherwise.
var now: NIODeadline { get }The current time of the event loop.
func _executeIsolatedUnsafeUnchecked(_ task: @escaping () -> Void) Submit a given task to be executed by the EventLoop, from a context where the caller statically knows that the context is isolated.
func _preconditionSafeToWait(file: StaticString, line: UInt) Must crash if it is not safe to call wait() on an EventLoopFuture.
func _promiseCompleted(futureIdentifier: _NIOEventLoopFutureIdentifier) -> (file: StaticString, line: UInt)? Debug hook: complete a specific promise and return its creation location.
func _promiseCreated(futureIdentifier: _NIOEventLoopFutureIdentifier, file: StaticString, line: UInt) Debug hook: track a promise creation and its location.
@discardableResult func _scheduleTaskIsolatedUnsafeUnchecked<T>(deadline: NIODeadline, _ task: @escaping () throws -> T) -> Scheduled<T> Schedule a task that is executed by this EventLoop at the given time, from a context where the caller statically knows that the context is isolated.
@discardableResult func _scheduleTaskIsolatedUnsafeUnchecked<T>(in: TimeAmount, _ task: @escaping () throws -> T) -> Scheduled<T> Schedule a task that is executed by this EventLoop after the given amount of time, from a context where the caller statically knows that the context is isolated.
func _submitIsolatedUnsafeUnchecked<T>(_ task: @escaping () throws -> T) -> EventLoopFuture<T> Submit a given task to be executed by the ``EventLoop```, from a context where the caller statically knows that the context is isolated.
func cancelScheduledCallback(_ scheduledCallback: NIOScheduledCallback) Cancel a scheduled callback.
func enqueue(_ job: consuming ExecutorJob) Submit a job to be executed by the EventLoop
@preconcurrency func execute(_ task: @escaping () -> Void) Submit a given task to be executed by the EventLoop
func preconditionInEventLoop(file: StaticString, line: UInt) Asserts that the current thread is the one tied to this EventLoop. Otherwise, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:).
func preconditionNotInEventLoop(file: StaticString, line: UInt) Asserts that the current thread is not the one tied to this EventLoop. Otherwise, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:).
@discardableResult @preconcurrency func scheduleCallback(at deadline: NIODeadline, handler: some (NIOScheduledCallbackHandler & Sendable)) throws -> NIOScheduledCallback Schedule a callback at a given time.
@discardableResult @preconcurrency func scheduleCallback(in amount: TimeAmount, handler: some (NIOScheduledCallbackHandler & Sendable)) throws -> NIOScheduledCallback Schedule a callback after given time.
@discardableResult @preconcurrency func scheduleTask<T>(deadline: NIODeadline, _ task: @escaping () throws -> T) -> Scheduled<T> Schedule a task that is executed by this EventLoop at the given time.
@discardableResult @preconcurrency func scheduleTask<T>(in: TimeAmount, _ task: @escaping () throws -> T) -> Scheduled<T> Schedule a task that is executed by this EventLoop after the given amount of time.
@preconcurrency func submit<T>(_ task: @escaping () throws -> T) -> EventLoopFuture<T> Submit a given task to be executed by the EventLoop. Once the execution is complete the returned EventLoopFuture is notified.
func makeSucceededVoidFuture() -> EventLoopFuture<Void> Default implementation of makeSucceededVoidFuture: Return a fresh future (which will allocate).
