Struct InMemoryMemoryProvenanceStore 

pub struct InMemoryMemoryProvenanceStore { /* private fields */ }

Thread-safe in-memory MemoryProvenanceStore. Useful for tests and for ephemeral deployments; production deployments should use the SQLite-backed store in chio-store-sqlite.

Trait Implementations

impl Default for InMemoryMemoryProvenanceStore

fn default() -> InMemoryMemoryProvenanceStore

Returns the “default value” for a type.

impl MemoryProvenanceStore for InMemoryMemoryProvenanceStore

fn append( &self, input: MemoryProvenanceAppend, ) -> Result<MemoryProvenanceEntry, MemoryProvenanceError>

Append a new entry, computing the chain linkage atomically.

fn get_entry( &self, entry_id: &str, ) -> Result<Option<MemoryProvenanceEntry>, MemoryProvenanceError>

Fetch an entry by its unique id. Returns Ok(None) when the id is absent; consumers should treat that as UnverifiedReason::NoProvenance when it happens during a read.

fn latest_for_key( &self, store: &str, key: &str, ) -> Result<Option<MemoryProvenanceEntry>, MemoryProvenanceError>

Fetch the most-recent entry for a (store, key) pair, or Ok(None) when no entry has ever been appended for that key.

fn verify_entry( &self, entry_id: &str, ) -> Result<ProvenanceVerification, MemoryProvenanceError>

Verify a specific entry: recompute its hash, confirm its prev_hash matches the entry that sits immediately before it (or the genesis marker for entry #1), and return ProvenanceVerification::Verified when everything checks out.

fn chain_digest(&self) -> Result<String, MemoryProvenanceError>

Aggregate digest of the chain – the hash of the tail entry, or MEMORY_PROVENANCE_GENESIS_PREV_HASH when the chain is empty. Useful for embedding into receipts as a snapshot marker.
