Enum Availability

Source 
#[repr(u32)]
pub enum Availability {
    Required = 1,
    Optional = 2,
    SameAsTarget = 3,
    Transitional = 4,
}
Expand description

Describes the expected availability of the capability.

Some capabilities may not be present on all system configurations. In those cases, the availability will be declared as OPTIONAL along the chains of exposes/offers/uses, and the capability would be routed from void on system configurations where it does not make sense to route or provide a particular capability (e.g. graphical capabilities on a headless system).
