Struct InMemoryUcanRevocationStore 

pub struct InMemoryUcanRevocationStore { /* private fields */ }

Reference revocation store: an Arc<RwLock<HashSet<String>>> of revoked CIDs. Suitable for tests and small in-process deployments.

Concurrency: every read takes a shared lock; revocations take an exclusive lock and run in O(1) average. The whole structure clones cheaply (Arc) so multiple subsystems (broker, dispatch, Tauri command) can share one revocation surface.

Not persistent — restarting the host process empties the set. Adopters that need durable revocation (celia) back the trait with their own SQLite-or-similar store.

Implementations

impl InMemoryUcanRevocationStore

pub fn new() -> Self

pub fn revoke(&self, ucan_cid: impl Into<String>)

Mark a CID as revoked. Idempotent — revoking the same CID twice is a no-op. Once revoked, Self::is_revoked returns true for the lifetime of the store (no un-revoke API by design; administrators issue a fresh UCAN instead).

pub fn len(&self) -> usize

Number of revoked CIDs currently in the store. Mostly useful for test assertions + diagnostics; production code should not rely on this for policy.

pub fn is_empty(&self) -> bool
