Struct GraphIdentifierNamespace 

pub struct GraphIdentifierNamespace { /* private fields */ }

Implementations

impl GraphIdentifierNamespace

pub fn new(scope: Option<&str>, generation: [u8; 16]) -> Self

pub fn key( &self, tag: u8, kind: GraphEntityKind, prefix: u32, graph: [u8; 16], ) -> [u8; 78]

pub fn legacy_graph_identity(&self, graph: &str) -> [u8; 16]

Legacy names identify only the original incarnation. New graph creation supplies a random identity; rename retains the original identity in its registry.

pub fn label_key(&self, graph: [u8; 16]) -> [u8; 78]

pub fn serializable_entity_object(&self) -> [u8; 16]

Logical graph entity observations share the physical entity scope and clear generation, independently of named graph membership or table row identities.

pub fn serializable_scope_object(&self) -> [u8; 16]

Clearing a namespace invalidates even an absent read from any earlier generation of that physical scope.

pub fn sequence_key(&self, graph: [u8; 16], label: u32) -> [u8; 78]

pub fn entity_key(&self, kind: GraphEntityKind, prefix: u32) -> [u8; 78]

pub fn entity_seed_key(&self, kind: GraphEntityKind, prefix: u32) -> [u8; 78]

pub fn hint_key(&self, kind: GraphEntityKind) -> [u8; 78]

pub fn observe_entity( &self, batch: &mut dyn KeyValueBatch, kind: GraphEntityKind, id: u64, ) -> StorageBackendResult<()>

Preserve a supplied physical identity before its evaluated record is published. The wire identity has a two-byte prefix and six-byte ordinal; observing one row does not certify that legacy rows were seeded.

pub fn observe_registry( &self, batch: &mut dyn KeyValueBatch, graph: &str, source: &str, ) -> StorageBackendResult<()>

Import durable counters encoded in a graph registry without assigning labels or evaluating graph behavior. Opaque legacy payloads retain their existing catalog contract.
