Enum Availability 

#[non_exhaustive]
pub enum Availability {
    Available,
    NotPortable,
}

Whether a built-in found in the command search may be executed

The command search may find a built-in that the current shell options do not allow to execute. Such a built-in is not ignored: the search does not fall through to an external utility. Instead, it is reported as unavailable so that the caller can tell the user why the built-in cannot be used.

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.

Available

The built-in may be executed.

NotPortable

The built-in, or the name under which it was found, is not defined in POSIX, and the Portable option rejects it.
