NAME

App::mirai::Future - injects debugging code into Future

VERSION

version 0.003

DESCRIPTION

On load, this will monkey-patch Future to provide various precarious hooks for Future-related events.

create_watcher

Returns a new App::mirai::Watcher.

 my $watcher = App::mirai::Future->create_watcher;
 $watcher->subscribe_to_event(
  create => sub { my ($ev, $f) = @_; warn "Created new future: $f\n" },
 );

delete_watcher

Deletes the given watcher.

 my $watcher = App::mirai::Future->create_watcher;
 App::mirai::Future->delete_watcher($watcher);

future

Returns information about the given Future instance.

futures

Returns all the Futures we know about.

MONKEY PATCHES

These reach deep into Future and are likely to break any time a new version is released.

Future::DESTROY

Hook destruction so we know when a Future is going away.

Future::set_label

Pick up any label changes, since Futures are created without them.
