Enum ServiceRefusal 

pub enum ServiceRefusal {
    NotAService,
    Binding(SubjectBindingError),
    Decision(AccessDecisionError),
    PolicyUnavailable,
    NoOperation,
    Effect(ServiceEffectError),
}

Why a subject was not served, by name.

Variants

NotAService

No service serves the subject.

Binding(SubjectBindingError)

The subject could not be bound.

Decision(AccessDecisionError)

The decision refused it: a missing grant, an expired pass, or the deliberate seam being absent or offline (deliberate_unavailable).

PolicyUnavailable

Lys holds no budget or stop policy for the holder; liminal sets none.

NoOperation

The request named no operation id, so its effect could not be made once; nothing was decided or done.

Effect(ServiceEffectError)

The effect failed after the grant allowed it.
