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

VERSION
       version 2.1005

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'.
