Instance Method

future()

Creates a new, succeeded EventLoopFuture from the worker’s event loop with a Void value.

func future() -> EventLoopFuture<Void>

Return Value

The succeeded future.

Let a: EventLoopFuture = req.future()

func flatten<T>([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([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: any Error) -> EventLoopFuture<T>
Creates a new, failed EventLoopFuture from the worker’s event loop.
func future<T>(T) -> EventLoopFuture<T>
Creates a new, succeeded EventLoopFuture from the worker’s event loop.
func future<T>(result: Result<T, any Error>) -> EventLoopFuture<T>
Creates a new Future from the worker’s event loop, succeeded or failed based on the input Result.
func tryFuture<T>(() 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.
