=head1 NAME
DBIx::Class::Helper::Row::SelfResultSet - Easily use ResultSet methods for the current row
=head1 VERSION
version 2.019004
=head1 SYNOPSIS
In result class:
__PACKAGE__->load_components('Helper::Row::SelfResultSet');
Elsewhere:
$row->self_rs->$some_rs_method->single
=head1 DESCRIPTION
Sometimes you need to be able to access a ResultSet containing just the current
row. A good reason to do that would be if you had a ResultSet method that adds
in some calculated data, like counts of a relationship. You could use this to
get at that counted data without duplicating the logic for the counting.
=head1 METHODS
=head2 self_rs
$row->self_rs
returns a ResultSet containing B<just> the current row.
