Test2::Util::Facets2Legacy - phpMan

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.
