constraint lifetime

These values represent different lifetime semantics. They are passed as arguments to the factory requests to specify how the constraint lifetimes should be managed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Oneshot

the pointer constraint is defunct once deactivated

A oneshot pointer constraint will never reactivate once it has been deactivated. See the corresponding deactivation event (wp_locked_pointer.unlocked and wp_confined_pointer.unconfined) for details.

Persistent

the pointer constraint may reactivate

A persistent pointer constraint may again reactivate once it has been deactivated. See the corresponding deactivation event (wp_locked_pointer.unlocked and wp_confined_pointer.unconfined) for details.
