Struct SubjectRef 

pub struct SubjectRef {
    pub object: ObjectRef,
    pub relation: Option<String>,
}

The subject half of a tuple: either a concrete object, or the userset object#relation — “everyone who holds relation on object”.

The userset form is what makes group nesting explicit (group:eng#member writer database:music); the plain form is expanded through crate::AuthzConfig::expand_relations so the shorter, more common spelling (group:eng writer database:music) also works.

Fields

object: ObjectRef

The object named on the subject side.

relation: Option<String>

Relation on that object, when the subject is a userset.

Implementations
