An EventLoop forms a singular EventLoopGroup, returning itself as the ‘next’ EventLoop.
func next() -> EventLoop Itself, because an EventLoop forms a singular EventLoopGroup.
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.
func next() -> EventLoop Returns the next EventLoop to use, this is useful for load balancing.

func _executeIsolatedUnsafeUnchecked(_ task: @escaping () -> Void) Default implementation: wraps the task in an UnsafeTransfer.
func _preconditionSafeToWait(file: StaticString, line: UInt) func _promiseCompleted(futureIdentifier: _NIOEventLoopFutureIdentifier) -> (file: StaticString, line: UInt)? Default implementation of _promiseCompleted: does nothing.
func _promiseCreated(futureIdentifier: _NIOEventLoopFutureIdentifier, file: StaticString, line: UInt) Default implementation of _promiseCreated: does nothing.

func any() -> EventLoop An EventLoop forms a singular EventLoopGroup, returning itself as ‘any’ EventLoop.
func assertInEventLoop(file: StaticString = #fileID, line: UInt = #line) 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 = #fileID, line: UInt = #line) 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 assumeIsolated() -> NIOIsolatedEventLoop Assumes the calling context is isolated to the event loop.
func assumeIsolatedUnsafeUnchecked() -> NIOIsolatedEventLoop Assumes the calling context is isolated to the event loop.

func makeSucceededVoidFuture() -> EventLoopFuture<Void> Default implementation of makeSucceededVoidFuture: Return a fresh future (which will allocate).
func preconditionInEventLoop(file: StaticString = #fileID, line: UInt = #line) Checks the necessary condition of currently running on the called EventLoop for making forward progress.
