=head1 NAME

Test2::EventFacet::Info - Facet for information a developer might care about.

=head1 DESCRIPTION

This facet represents messages intended for humans that will help them either
understand a result, or diagnose a failure.

=head1 NOTES

This facet appears in a list instead of being a single item.

=head1 FIELDS

=over 4

=item $string_or_structure = $info->{details}

=item $string_or_structure = $info->details()

Human readable string or data structure, this is the information to display.
Formatters are free to render the structures however they please. This may
contain a blessed object.

If the C<table> attribute (see below) is set then a renderer may choose to
display the table instead of the details.

=item $structure = $info->{table}

=item $structure = $info->table()

If the data the C<info> facet needs to convey can be represented as a table
then the data may be placed in this attribute in a more raw form for better
display. The data must also be represented in the C<details> attribute for
renderers which do not support rendering tables directly.

The table structure:

    my %table = {
        header => [ 'column 1 header', 'column 2 header', ... ], # Optional

        rows => [
            ['row 1 column 1', 'row 1, column 2', ... ],
            ['row 2 column 1', 'row 2, column 2', ... ],
            ...
        ],

        # Allow the renderer to hide empty columns when true, Optional
        collapse => $BOOL,

        # List by name or number columns that should never be collapsed
        no_collapse => \@LIST,
    }

=item $short_string = $info->{tag}

=item $short_string = $info->tag()

Short tag to categorize the info. This is usually 10 characters or less,
formatters may truncate longer tags.

=item $bool = $info->{debug}

=item $bool = $info->debug()

Set this to true if the message is critical, or explains a failure. This is
info that should be displayed by formatters even in less-verbose modes.

When false the information is not considered critical and may not be rendered
in less-verbose modes.

=item $bool = $info->{important}

=item $bool = $info->important

This should be set for non debug messages that are still important enough to
show when a formatter is in quiet mode. A formatter should send these to STDOUT
not STDERR, but should show them even in non-verbose mode.
