IO::Async::Future(3pm)User Contributed Perl DocumentatioIO::Async::Future(3pm) NAME "IO::Async::Future" - use Future with IO::Async SYNOPSIS use IO::Async::Loop; my $loop = IO::Async::Loop->new; my $future = $loop->new_future; $loop->watch_time( after => 3, code => sub { $future->done( "Done" ) } ); print $future->get, "\n"; DESCRIPTION This subclass of Future stores a reference to the IO::Async::Loop instance that created it, allowing the "await" method to block until the Future is ready. These objects should not be constructed directly; instead the "new_future" method on the containing Loop should be used. For a full description on how to use Futures, see the Future documentation. CONSTRUCTORS New "IO::Async::Future" objects should be constructed by using the following methods on the "Loop". For more detail see the IO::Async::Loop documentation. $future = $loop->new_future Returns a new pending Future. $future = $loop->delay_future( %args ) Returns a new Future that will become done at a given time. $future = $loop->timeout_future( %args ) Returns a new Future that will become failed at a given time. METHODS loop $loop = $future->loop Returns the underlying IO::Async::Loop object. done_later $future->done_later( @result ) A shortcut to calling the "done" method in a "later" idle watch on the underlying Loop object. Ensures that a returned Future object is not ready immediately, but will wait for the next IO round. Like "done", returns $future itself to allow easy chaining. fail_later $future->fail_later( $exception, @details ) A shortcut to calling the "fail" method in a "later" idle watch on the underlying Loop object. Ensures that a returned Future object is not ready immediately, but will wait for the next IO round. Like "fail", returns $future itself to allow easy chaining.
