=head1 NAME

Test2::Hub::Subtest - Hub used by subtests

=head1 DESCRIPTION

Subtests make use of this hub to route events.

=head1 TOGGLES

=over 4

=item $bool = $hub->manual_skip_all

=item $hub->set_manual_skip_all($bool)

The default is false.

Normally a skip-all plan event will cause a subtest to stop executing. This is
accomplished via C<last LABEL> to a label inside the subtest code. Most of the
time this is perfectly fine. There are times however where this flow control
causes bad things to happen.

This toggle lets you turn off the abort logic for the hub. When this is toggled
to true B<you> are responsible for ensuring no additional events are generated.
