Instance Method
flatten(on:)
Converts a collection of
EventLoopFuture<Void>s to an EventLoopFuture<Void>.func flatten(on eventLoop: any EventLoop) -> EventLoopFuture<Void>Parameters
eventLoopThe event-loop to succeed the futures on.
Return Value
The succeeded future.
Discussion
Acts as a helper for the EventLoop.flatten(_:[EventLoopFuture<Value>]) method.
let futures = [el.future(1), el.future(2), el.future(3), el.future(4)]
let flattened = futures.flatten(on: el)
// flattened: EventLoopFuture<Void>
