Enum ResourceRef 

pub enum ResourceRef {
    Uuid(Uuid),
    Name(ResourceName),
    Undefined,
}

A reference to a resource, by id, by name, or unspecified.

A resource can be addressed two ways: by its stable Uuid or by its human-readable ResourceName. Undefined is a third state for when no particular resource is meant (a wildcard), used chiefly in policy checks.

Variants

Uuid(Uuid)

References a resource by its stable unique identifier.

Name(ResourceName)

References a resource by its hierarchical ResourceName.

Undefined

Not referencing a specific resource.

This is used to represent a wildcard in a policy which can be useful to check if a user can create or manage resources at a specific level.
