Struct ProofCache 

pub struct ProofCache { /* private fields */ }

Implementations

impl ProofCache

pub fn open(path: PathBuf, signer: &ProofSigner) -> Result<Self>

Open (and signature-verify) the cache at path. Missing files are treated as empty caches.

pub fn insert(&self, proof: Proof) -> Result<()>

Insert a (presumably just-minted, already-signed) proof and persist the cache. Replaces any existing proof for the same (provider, subject, scope) tuple – one slot per identity per scope, so re-verifying simply refreshes the timestamp.

pub fn flush(&self) -> Result<usize>

Drop every cached proof. Returns the number evicted.

pub fn find_satisfying(&self, req: &Requirement, now: u64) -> Option<Proof>

Find any proof that satisfies req at now. Returns the proof with the latest verified_at if multiple match (most-recently- verified wins).

pub fn count_valid(&self, now: u64) -> usize

How many proofs are currently cached AND not expired at now.
