NAME

       Test2::Util::Facets2Legacy - Convert facet data to the legacy event API.

DESCRIPTION

       This module exports several subroutines from the older event API (see Test2::Event). These
       subroutines can be used as methods on any object that provides a custom "facet_data()"
       method. These subroutines can also be used as functions that take a facet data hashref as
       arguments.

SYNOPSIS

   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;
           ....

   AS FUNCTIONS
           use Test2::Util::Facets2Legacy ':ALL';

           my $f = {
               assert => { ... },
               info => [{...}, ...],
               control => {...},
               ...
           };

           my $causes_fail = causes_fail($f);
           my $summary     = summary($f);

NOTE ON CYCLES

       When used as methods, all these subroutines call "$e->facet_data()". The default
       "facet_data()" method in Test2::Event 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. "uuid()" is currently the only subroutine in this library that has a fallback
       behavior when cycles are detected.

EXPORTS

       Nothing is exported by default. You must specify which methods to import, or use the
       ':ALL' tag.

       $bool = $e->causes_fail()
       $bool = causes_fail($f)
           Check if the event or facets result in a failing state.

       $bool = $e->diagnostics()
       $bool = diagnostics($f)
           Check if the event or facets contain any diagnostics information.

       $bool = $e->global()
       $bool = global($f)
           Check if the event or facets need to be globally processed.

       $bool = $e->increments_count()
       $bool = increments_count($f)
           Check if the event or facets make an assertion.

       $bool = $e->no_display()
       $bool = no_display($f)
           Check if the event or facets should be rendered or hidden.

       ($max, $directive, $reason) = $e->sets_plan()
       ($max, $directive, $reason) = sets_plan($f)
           Check if the event or facets set a plan, and return the plan details.

       $id = $e->subtest_id()
       $id = subtest_id($f)
           Get the subtest id, if any.

       $string = $e->summary()
       $string = summary($f)
           Get the summary of the event or facets hash, if any.

       $undef_or_int = $e->terminate()
       $undef_or_int = terminate($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.

       $uuid = $e->uuid()
       $uuid = uuid($f)
           Get the UUID of the facets or event.

           Note: This will fall back to "$e->SUPER::uuid()" if a cycle is detected and an event
           is used as the argument.
