Enum AccompanimentProblem 

#[non_exhaustive]
pub enum AccompanimentProblem {
    Reference {
        reference: BACnetDeviceObjectReference,
        reason: AccompanimentReferenceFailure,
    },
    Property {
        object: ObjectIdentifier,
        property: PropertyIdentifier,
        detail: String,
    },
    Rights {
        presentation: u64,
        detail: String,
    },
    MissingWitness {
        presentation: u64,
    },
    AmbiguousWitness {
        presentation: u64,
    },
    Presentation {
        presentation: u64,
        reason: AccompanimentPresentationFailure,
    },
    CyclicRequirement {
        path: Vec<CredentialPresentation>,
    },
    LinkLimit {
        max_links: usize,
    },
}

Evidence preventing an accompaniment-stage conclusion. These conditions do not invent BACnet denial events or override the existing rights policy.

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.

Reference

A selected requirement or relevant ownership reference is unavailable.

Fields

reference: BACnetDeviceObjectReference

The reference that could not be established.

reason: AccompanimentReferenceFailure

The local resolution limit.

Property

A served property could not be read or decoded as its required type.

Fields

object: ObjectIdentifier

Object serving the property.

property: PropertyIdentifier

Property read.

detail: String

Original error or datatype diagnostic.

Rights

No rights result could be obtained for a received companion. Excluded assignments in a successful rights result are diagnostics instead.

Fields

presentation: u64

Presentation whose rights read failed.

detail: String

Error from the existing rights evaluator.

MissingWitness

The caller supplied no state for a required dependency.

Fields

presentation: u64

Presentation needing a witness.

AmbiguousWitness

More than one witness names the same dependency.

Fields

presentation: u64

Presentation with conflicting witness rows.

Presentation

A presentation or deadline assertion is inconsistent or ineligible.

Fields

presentation: u64

Presentation whose evidence is at issue.

reason: AccompanimentPresentationFailure

The failed consistency check.

CyclicRequirement

A dependency returns to an earlier credential/presentation after a distinct companion. No cyclic fixed-point authorization is assumed.

Fields

path: Vec<CredentialPresentation>

Traversed presentations followed by the repeated dependency.

LinkLimit

The caller’s finite traversal budget was exhausted.

Fields

max_links: usize

Maximum permitted dependency links.
