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.

memory::InMemoryResolver

An in-memory DID resolver for testing and development.

Stores documents in a thread-safe HashMap. Documents are registered via register and resolved via the [Resolver] trait.

Thread Safety

Uses RwLock for interior mutability, allowing concurrent reads with exclusive writes.

Examples

use oas_resolve::memory::InMemoryResolver;
use oas_resolve::resolver::Resolver;
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;
assert!(resolved.is_ok());
# });

pub struct InMemoryResolver {

}

Source line: 52.

memory::InMemoryResolver::new

Creates an empty in-memory resolver.

pub fn new() -> Self;

Source line: 58.

memory::InMemoryResolver::register

Registers a document in the resolver.

The document is stored under its id field. If a document with the same ID already exists, it is replaced.

Arguments

• doc - The document to register.

pub fn register(&self, doc: OasDocument);

Source line: 72.

memory::InMemoryResolver::len

Returns the number of registered documents.

pub fn len(&self) -> usize;

Source line: 79.

memory::InMemoryResolver::is_empty

Returns true if no documents are registered.

pub fn is_empty(&self) -> bool;

Source line: 84.

memory::InMemoryResolver::remove

Removes a document from the resolver.

Arguments

• did - The DID of the document to remove.

Returns

The removed document, if it existed.

pub fn remove(&self, did: &str) -> Option<OasDocument>;

Source line: 97.
