NAME
       Moose::Meta::Attribute::Native::Trait::Bool - Helper trait for Bool attributes

VERSION
       version 2.0604

SYNOPSIS
         package Room;
         use Moose;

         has 'is_lit' => (
             traits  => ['Bool'],
             is      => 'rw',
             isa     => 'Bool',
             default => 0,
             handles => {
                 illuminate  => 'set',
                 darken      => 'unset',
                 flip_switch => 'toggle',
                 is_dark     => 'not',
             },
         );

         my $room = Room->new();
         $room->illuminate;        # same as $room->is_lit(1);
         $room->darken;            # same as $room->is_lit(0);
         $room->flip_switch;       # same as $room->is_lit(not $room->is_lit);
         return $room->is_dark;    # same as !$room->is_lit

DESCRIPTION
       This trait provides native delegation methods for boolean values. A boolean is a scalar which can be
       1, 0, "", or "undef".

DEFAULT TYPE
       If you don't provide an "isa" value for your attribute, it will default to "Bool".

PROVIDED METHODS
       None of these methods accept arguments.

       •   set

           Sets the value to 1 and returns 1.

       •   unset

           Set the value to 0 and returns 0.

       •   toggle

           Toggles the value. If it's true, set to false, and vice versa.

           Returns the new value.

       •   not

           Equivalent of 'not $value'.
