These subroutines can be used as methods on any object that provides a custom C method. These subroutines can also be used as functions that take a facet data hashref as arguments. =head1 SYNOPSIS =head2 AS METHODS package My::Event; use Test2::Util::Facets2Legacy ':ALL'; sub facet_data { return { ... } } Then to use it: my $e = My::Event->new(...); my $causes_fail = $e->causes_fail; my $summary = $e->summary; .... =head2 AS FUNCTIONS use Test2::Util::Facets2Legacy ':ALL'; my $f = { assert => { ... }, info => [{...}, ...], control => {...}, ... }; my $causes_fail = causes_fail($f); my $summary = summary($f); =head1 NOTE ON CYCLES When used as methods, all these subroutines call C<< $e->facet_data() >>. The default C method in L relies on the legacy methods this module emulates in order to work. As a result of this it is very easy to create infinite recursion bugs. These methods have cycle detection and will throw an exception early if a cycle is detected. C is currently the only subroutine in this library that has a fallback behavior when cycles are detected. =head1 EXPORTS Nothing is exported by default. You must specify which methods to import, or use the ':ALL' tag. =over 4 =item $bool = $e->causes_fail() =item $bool = causes_fail($f) Check if the event or facets result in a failing state. =item $bool = $e->diagnostics() =item $bool = diagnostics($f) Check if the event or facets contain any diagnostics information. =item $bool = $e->global() =item $bool = global($f) Check if the event or facets need to be globally processed. =item $bool = $e->increments_count() =item $bool = increments_count($f) Check if the event or facets make an assertion. =item $bool = $e->no_display() =item $bool = no_display($f) Check if the event or facets should be rendered or hidden. =item ($max, $directive, $reason) = $e->sets_plan() =item ($max, $directive, $reason) = sets_plan($f) Check if the event or facets set a plan, and return the plan details. =item $id = $e->subtest_id() =item $id = subtest_id($f) Get the subtest id, if any. =item $string = $e->summary() =item $string = summary($f) Get the summary of the event or facets hash, if any. =item $undef_or_int = $e->terminate() =item $undef_or_int = terminate($f) Check if the event or facets should result in process termination, if so the exit code is returned (which could be 0). undef is returned if no termination is requested. =item $uuid = $e->uuid() =item $uuid = uuid($f) Get the UUID of the facets or event. B This will fall back to C<< $e->SUPER::uuid() >> if a cycle is detected and an event is used as the argument. =back =head1 SOURCE The source code repository for Test2 can be found at F. =head1 MAINTAINERS =over 4 =item Chad Granum Eexodist@cpan.orgE =back =head1 AUTHORS =over 4 =item Chad Granum Eexodist@cpan.orgE =back =head1 COPYRIGHT Copyright 2020 Chad Granum Eexodist@cpan.orgE.
