Crate lora_store 

Storage layer: graph value types, the trait surface every backend implements, and the in-memory reference backend.

Public surface is laid out here so the full export of the crate is readable in one place.

Modules

types

Storage-layer value types — the vocabulary every backend speaks.

Structs

ClosureRecorder

Convenience adapter that turns any Fn(MutationEvent) + Send + Sync into a MutationRecorder — useful in tests and for quick wiring.

InMemoryGraph

LockTable

Sharded per-record write-lock registry. Cloning is cheap (one Arc per shard map) so the table can live behind an Arc shared across all writers.

MutationWriteSet

Set of record ids touched by a buffered MutationEvent stream.

SnapshotMeta

Metadata reported by snapshot encode / decode entry points. Kept small and stable so callers can log / diff it without reflecting on the payload.

SnapshotPayload

Portable representation of an entire store state.

WriteSetLocks

Bundle of per-record locks held by a single writer’s commit critical section. Holding the locks here (rather than scattered MutexGuards) makes drop order deterministic — all locks release when this struct drops, regardless of which release path (commit / abort / panic) the writer took.

Enums

MutationEvent

A durable, replayable mutation against a graph store.

SnapshotError

Errors a backend may surface while building or restoring a snapshot payload. Codec-level errors live in [lora-snapshot]; these are the store-side payload-shaped failures.

Constants

LOCK_TABLE_SHARDS

Power-of-two number of shards in the lock table. Chosen large enough that per-shard contention is well below per-record contention for any realistic thread count, small enough that the table itself stays under a few KB of empty-shard overhead.

Traits

BorrowedGraphStorage

GraphCatalog

GraphStorage

GraphStorageMut

MutationRecorder

Observer that receives every successful mutation in the order the store applied it.
