# slap_snapshot_log v0.3.0 - Table of Contents > An append-only log with snapshots that replace its prefix, on Slap.Streams. ## Pages - [slap_snapshot_log](readme.md) - [Changelog](changelog.md) - [LICENSE](license.md) ## Modules - [Slap.SnapshotLog](Slap.SnapshotLog.md): An append-only log of opaque entries, with snapshots that replace its prefix, stored in Durable Streams (`Slap.Streams`) below a base path. A consumer rebuilds its state from the current snapshot and the entries after it, follows the log to stay current, and publishes snapshots of what it has applied, which trims the entries they cover.
