EventLoop and EventLoopGroup

  • flatten(_:)
    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.
  • flatten(_:)
    Returns a new EventLoopFuture that succeeds only when all the provided futures succeed, ignoring the resolved values.
  • future()
    Creates a new, succeeded EventLoopFuture from the worker’s event loop with a Void value.
  • future(error:)
    Creates a new, failed EventLoopFuture from the worker’s event loop.
  • future(_:)
    Creates a new, succeeded EventLoopFuture from the worker’s event loop.
  • tryFuture(_:)
    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.
