This provides a simple boolean attribute, which supports most of the basic math
operations.
These methods are implemented in MouseX::NativeTraits::MethodProvider::Bool. It
is important to note that all those methods do in place modification of the
value stored in the attribute.
- set
- Sets the value to true.
- unset
- Set the value to false.
- toggle
- Toggles the value. If it's true, set to false, and vice versa.
- not
- Equivalent of 'not $value'.
- meta
- method_provider_class
