This source reference follows declared modules and preserves feature attributes. It includes public declarations and implementation methods in those modules. Private-module exports and trait resolution still require the compiler; not every declaration is a crate-root import. Function bodies and constant values are omitted. Source comments describe their implementation context and are not a production deployment claim.

oas-resolve

DID resolution for the Open Agent Specification (OAS).

This crate provides the Resolver trait and several implementations for resolving did:oas identifiers to OAS Identity Documents.

Key Types

• Resolver — The core async resolution trait
• InMemoryResolver — In-memory resolver for testing
• CachingResolver — TTL-based caching wrapper
• FallbackResolver — Priority-ordered fallback chain
• [ResolveError] — Resolution errors with OAS §12.5 error codes
• ResolutionMetadata — Resolution process metadata

Design

Per OAS Specification §12, resolution is defined as an abstract protocol. This crate provides the trait and utility implementations. Concrete backends (DHT, HTTP, blockchain) implement the Resolver trait.

Example

use oas_resolve::resolver::Resolver;
use oas_resolve::memory::InMemoryResolver;
use oas_document::builder::DocumentBuilder;
use oas_document::conformance::ConformanceLevel;
use oas_crypto::keypair::OasKeyPair;

# tokio_test::block_on(async {
let keypair = OasKeyPair::generate();
let doc = DocumentBuilder::new("did:oas:test:hmr:alice", "hmr")
    .conformance_level(ConformanceLevel::L1)
    .add_verification_method(&keypair)
    .build_and_sign(&keypair, "2026-01-15T00:00:00Z")
    .unwrap();

let resolver = InMemoryResolver::new();
resolver.register(doc);

let resolved = resolver.resolve("did:oas:test:hmr:alice").await.unwrap();
assert_eq!(resolved.id, "did:oas:test:hmr:alice");
# });
