Module snapshot 

Structs

DiskSnapshotStore

Disk-backed snapshot store. Writes are atomic via the .tmp + rename dance in crate::atomic::write_atomic_bytes, with the parent directory fsynced on success.

MemorySnapshotStore

No-op store used in StorageMode::Memory. load always returns None and save is a noop.

Traits

SnapshotStore

Generic opaque-blob snapshot store used by services that persist their whole state as a single serialized document (DynamoDB tables, SQS queues, etc.). Unlike the fine-grained crate::s3::S3Store which tracks individual objects and streams bodies to disk, this trait is designed for services whose state is small enough to fit in memory and can be written as one atomic file.
