Implementations

impl CircleSnapshotMeta

pub fn signed( store_root_hash: ObjectHash, circle_id: CircleId, author_registration: StoreDeviceRegistrationRef, control: CircleControlCoord, epoch_id: CircleEpochId, key_fingerprint: KeyFingerprint, generation: u64, bootstrap: CircleBootstrapRef, created_at: String, successor: CircleSnapshotSuccessorLink, device_signer: &UserKeypair, ) -> Result<Self, StoreProtocolError>

pub fn snapshot_hash(&self) -> ObjectHash

pub fn semantic_hash_from_bytes( bytes: &[u8], ) -> Result<ObjectHash, StoreProtocolError>

pub fn parse_at( bytes: &[u8], expected_store_root_hash: ObjectHash, expected: &CircleSnapshotRef, author: &StoreDeviceRegistration, ) -> Result<Self, StoreProtocolError>

Verify one exact Circle snapshot against its expected reference and author registration. The successor’s stream activation is not recomputed here: a Circle snapshot stream has no per-(device, Circle) first slot in the registration for a reader to derive, so the create-once successor slot and predecessor chain establish stream position, exactly as the Circle acknowledgement stream does.
