Crate atomr_persistence_tck 

atomr-persistence-tck.

Provides reusable spec functions plugin authors can call against their Journal and SnapshotStore implementations.

The suite is split into journal_suite and snapshot_suite modules (plus the lightweight round-trip helpers retained for historical usage).

Functions

journal_concurrent_suite

Concurrent-writer interleaving. Writes batches for two distinct persistence ids concurrently; both replays must observe a contiguous sequence with no cross-id leakage.

journal_extended_suite

Extended suite covering edge cases drawn from upstream’s Replay-from-mid, replay-after-delete, idempotent replay, max=0 short-circuit, and concurrent-writer interleaving.

journal_replay_edge_cases

Edge-case replay assertions: empty pid, replay past the end, delete-to-zero, replay against a deleted prefix. Mirrors a subset of upstream JournalSpec’s “additional behaviour” suite.

journal_round_trip

Simple write/replay round trip. Returns true on success.

journal_suite

Full journal conformance suite. Panics with a descriptive message on the first failing assertion so callers can wire it straight into #[tokio::test] without additional boilerplate.

journal_tag_suite

Conformance for optional tag-based querying. Callers gate this on a supports_tags capability flag since not every backend implements it.

snapshot_extended_suite

Extended snapshot conformance suite. Covers: latest-wins across multiple saves, cross-pid isolation, partial deletes, no-op deletes against unknown pids, and concurrent saves for the same pid.

snapshot_round_trip

Smoke test: save and load a single snapshot.

snapshot_suite

Full snapshot conformance suite.
