Struct DidDocument 

pub struct DidDocument {
    pub id: String,
    pub verification_method: Vec<VerificationMethod>,
    pub assertion_method: Vec<Value>,
    pub key_agreement: Vec<VerificationMethod>,
}

A DID Document, parsed to the fields APH needs.

Deliberately NOT deny_unknown_fields: a DID Document is a general W3C artifact that legitimately carries much more than APH reads (services, authentication relationships, other proof purposes). Rejecting those would make APH unable to verify notaries with ordinary DID Documents.

Fields

id: String

The document’s own DID.

verification_method: Vec<VerificationMethod>

Published keys. Absent in a document that delegates all keys by reference, which APH cannot use.

assertion_method: Vec<Value>

DID URLs approved for the assertionMethod proof purpose.

key_agreement: Vec<VerificationMethod>

Key-agreement (encryption) keys — the surface RFC 0008’s sealed payloads resolve readers from. APH’s profile carries EMBEDDED entries (the same Multikey shape as verificationMethod), never bare string references: a reference points at a key the resolver must fetch AGAIN, and the §8.4 surfaces publish whole documents.

Implementations

impl DidDocument

pub fn key_agreement_x25519(&self, kid: &str) -> Result<[u8; 32], AphError>

Resolves the X25519 keyAgreement key named by kid — the reader key a sealed payload (RFC 0008) points at. Refuses with APH_E023 when the document publishes no matching entry, when the entry carries no publicKeyMultibase, or when the bytes are not an X25519 multikey — all three are “the key you were told to use is not published”, and which document surface came up empty is exactly what the code’s distinctness from APH_E014 exists to say.

pub fn allows_assertion(&self, did_url: &str) -> bool

Returns true if did_url is listed for the assertionMethod proof purpose, which is the purpose APH envelope proofs declare.

Entries may be plain DID URL strings or embedded objects with an id; both forms are recognized.

pub fn resolve_key(&self, did_url: &str) -> Result<NotaryPublicKey, AphError>

Finds the key a proof’s verificationMethod names (spec §8.4.4 steps 5–6).

When the DID URL carries no fragment, the document must publish exactly one key: guessing among several would let the document’s ordering decide which key verifies a credential.
