+=head1 NAME
+
+C<IO::Async::Future> - use L<Future> with L<IO::Async>
+
+=head1 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";
+
+=head1 DESCRIPTION
+
+This subclass of L<Future> stores a reference to the L<IO::Async::Loop>
+instance that created it, allowing the C<await> method to block until the
+Future is ready. These objects should not be constructed directly; instead
+the C<new_future> method on the containing Loop should be used.
+
+For a full description on how to use Futures, see the L<Future> documentation.
+

+
+=head1 CONSTRUCTORS
+
+New C<IO::Async::Future> objects should be constructed by using the following
+methods on the C<Loop>. For more detail see the L<IO::Async::Loop>
+documentation.
+
+=head2 $future = $loop->new_future
+
+Returns a new pending Future.
+
+=head2 $future = $loop->delay_future( %args )
+
+Returns a new Future that will become done at a given time.
+
+=head2 $future = $loop->timeout_future( %args )
+
+Returns a new Future that will become failed at a given time.
+

+sub new
+{
+   my $proto = shift;
+   my $self = $proto->SUPER::new;
+
+   if( ref $proto ) {
+      $self->{loop} = $proto->{loop};
+   }
+   else {
+      $self->{loop} = shift;
+   }
+
+   return $self;
+}
+
+=head1 METHODS
+
+=cut
+
+=head2 $loop = $future->loop
+
+Returns the underlying C<IO::Async::Loop> object.

+
+sub loop
+{
+   my $self = shift;
+   return $self->{loop};
+}
+
+sub await
+{
+   my $self = shift;
+   $self->{loop}->loop_once;
+}
+
+=head2 $future->done_later( @result )
+
+A shortcut to calling the C<done> method in a C<later> idle watch on the
+underlying Loop object. Ensures that a returned Future object is not ready
+immediately, but will wait for the next IO round.
+
+Like C<done>, returns C<$future> itself to allow easy chaining.

+}
+
+=head2 $future->fail_later( $exception, @details )
+
+A shortcut to calling the C<fail> method in a C<later> idle watch on the
+underlying Loop object. Ensures that a returned Future object is not ready
+immediately, but will wait for the next IO round.
+
+Like C<fail>, returns C<$future> itself to allow easy chaining.
