future
Creates a new, succeeded EventLoopFuture from the worker’s event loop with a Void value.
func future() -> EventLoopFuture<Void> Returns
The succeeded future.
let a: EventLoopFuture
Creates a new, succeeded EventLoopFuture from the worker’s event loop with a Void value.

import NIOCoreThe core abstractions that make up SwiftNIO.
import AsyncKitProvides a set of utilities for working with EventLoopFutures and other pre-Concurrency support APIs.
protocol EventLoopGroup : AnyObject, _NIOPreconcurrencySendableProvides an endless stream of EventLoops to use.
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 ().
func flatten<T>(_ futures: [EventLoopFuture<T>]) -> EventLoopFuture<[T]> Returns a new EventLoopFuture that succeeds only when all the provided futures succeed. The new EventLoopFuture contains an array of results, maintaining same ordering as the futures.
func flatten(_ futures: [EventLoopFuture<Void>]) -> EventLoopFuture<Void> Returns a new EventLoopFuture that succeeds only when all the provided futures succeed, ignoring the resolved values.
func future<T>(error: Error) -> EventLoopFuture<T> Creates a new, failed EventLoopFuture from the worker’s event loop.
func future<T>(_ value: T) -> EventLoopFuture<T> Creates a new, succeeded EventLoopFuture from the worker’s event loop.
func future<T>(result: Result<T, Error>) -> EventLoopFuture<T> Creates a new Future from the worker’s event loop, succeeded or failed based on the input Result.
func tryFuture<T>(_ work: @escaping () throws -> T) -> EventLoopFuture<T> An alternate name for this would be future(catching:), but with that name, trailing closure syntax just looks like el.future { ... }, which does not indicate to readers of the code that it is the error-capturing version. Since such an indication is highly desirable, a slightly less idiomatic name is used instead.
func makeFutureWithTask<Value>(_ body: @escaping () async throws -> Value) -> EventLoopFuture<Value> func performWithTask<Value>(_ body: @escaping () async throws -> Value) -> EventLoopFuture<Value> Run the async function body on an event loop in this group and return its result as an EventLoopFuture.
