NAME
"IO::Async::Loop::AnyEvent" - use "IO::Async" with "AnyEvent"
SYNOPSIS
use IO::Async::Loop::AnyEvent;
my $loop = IO::Async::Loop::AnyEvent->new();
$loop->add( ... );
$loop->add( IO::Async::Signal->new(
name => 'HUP',
on_receipt => sub { ... },
) );
$loop->loop_forever();
DESCRIPTION
This subclass of IO::Async::Loop uses AnyEvent to perform its work.
CONSTRUCTOR
$loop = IO::Async::Loop::AnyEvent->new
This function returns a new instance of a "IO::Async::Loop::AnyEvent"
object.
BUGS
* "watch_idle" and "unwatch_idle" don't work properly against
"AnyEvent::Impl::IOAsync". At least, the unit tests fail, and some
scheduled CODErefs never get executed, and sit in the internal queue
of the inner-nested "IO::Async::Loop" that "AnyEvent::Impl::IOAsync"
itself constructed. An easy workaround here is simply to pick
another AnyEvent model, by using the "PERL_ANYEVENT_MODEL"
environment variable.
That all said, I am honestly surprised this is the only thing that
breaks, when "IO::Async" is nested upon "AnyEvent" itself running
atop another "IO::Async".
* The implementation of the "loop_once" method requires the use of an
undocumented method "AnyEvent->one_event". This happens to work at
the time of writing, but as it is undocumented it may be subject to
change.
The "loop_forever" method does not rely on this undocumented method,
so should be safe from upstream changes. Furthremore, if "AnyEvent"
rather than "IO::Async" remains ultimately in control of the
runtime, by waiting on condvars, this should not be problematic.
