Struct CredentialStatusEntry 

pub struct CredentialStatusEntry {
    pub id: Option<String>,
    pub type: StatusEntryType,
    pub status_purpose: StatusPurpose,
    pub status_list_index: String,
    pub status_list_credential: String,
}

The status reference an envelope carries at top-level credentialStatus (spec §6.3.3.1, §7.1.1).

Whose status this is. In W3C VC 2.0 credentialStatus describes the credential carrying it. In APH it describes the parent Delegation Mandate named by credentialSubject.policy.delegationMandateId: an issued envelope stays cryptographically valid whatever happens afterwards, and revocation applies to Delegation Mandates only.

Fields

id: Option<String>

Identifier for this status entry. Omitted when absent.

type: StatusEntryType

Always StatusEntryType::BitstringStatusListEntry.

status_purpose: StatusPurpose

Always StatusPurpose::Revocation.

status_list_index: String

This mandate’s position in the list, a base-10 integer in a JSON string (§6.3.3.6).

A String on the wire AND in Rust, never a numeric type. In runtimes where every JSON number is an IEEE-754 double, an index past 2^53 is silently rounded — and a rounded index does not raise a parse error, it reads a DIFFERENT BIT, so the verifier answers a question about some other mandate with full confidence. Typing the field String makes a JSON number a deserialization failure instead of a wrong answer. Self::index is the only way to a number, and it goes through u64.

status_list_credential: String

Absolute https: URL of the status list credential. Bound same-origin against the derived endpoint before it is ever fetched (§6.3.3.2).

Implementations

impl CredentialStatusEntry

pub fn index(&self) -> Result<u64, AphError>

Parses Self::status_list_index as a base-10 u64 (§6.3.3.6).

Errors

APH_E008 for anything that is not a base-10 integer inside u64. §6.3.3.1 routes a malformed status reference to §8.3 step 1, but the §11 taxonomy is a CLOSED set of seventeen with no “malformed envelope” code; APH_E008 is §6.3.3.4 case 2 — “the verifier could not establish the status” — which is literally what an unreadable index leaves. The envelope is refused either way; only the reported code differs.
