Module persistence 

Session persistence: backend-agnostic configuration and runtime dispatch.

SessionPersistence is the configuration passed to ClientBuilder::persistence. Build it from a dedicated backend builder (FilePersistence or, with the turso feature, TursoPersistence), which each expose only their own options; they convert into a SessionPersistence via From.

At connect time it is turned into a Persistence, the runtime backend the connection event loop drives via Persistence::persist. This module knows nothing about any particular backend’s storage; each backend module owns its config, runtime store, and build. All backends share the same retry-safe contract: accumulated ops are cleared from the in-memory session only once they have been durably persisted, so a failed write keeps them buffered for the next attempt.

Modules

file 🔒

CRC-framed journal-file persistence backend.

turso 🔒 turso

Optional [turso] persistence backend.

Structs

FilePersistence

Configures session persistence backed by a CRC-framed journal file.

SessionPersistence

How a client’s session is durably persisted across restarts.

TursoPersistenceturso

Configures session persistence backed by a turso database.

Enums

Inner 🔒

The selected backend. Hidden so the variant set stays private: callers only construct (via the backend builders), never match.

Persistence 🔒

The runtime backend a connection persists its session ops to.
