miniproto.session.storage.EncryptedSQLiteSessionStorage.mutate

mutate(transform: Callable[[Mapping[str, Any] | None], SessionPayload | None]) -> Mapping[str, Any] | None

Atomically transform detached state under SQLite’s write transaction.

The transform must be synchronous; it executes while the backend lock and BEGIN IMMEDIATE transaction ensure no lost update.

Parameters:

• transform (Callable[[Mapping[str, Any] | None], SessionPayload | None]) – Synchronous callback receiving a detached current snapshot.
