Implementations

impl StateStore

pub fn export_persisted(&self) -> Result<PersistedState, StateError>

pub fn restore_persisted( &self, persisted: PersistedState, unknown_policy: UnknownKeyPolicy, ) -> Result<(), StateError>

pub fn restore_thread_scoped( &self, persisted: PersistedState, unknown_policy: UnknownKeyPolicy, ) -> Result<(), StateError>

Restore only Thread-scoped keys from a persisted state snapshot.

Run-scoped keys in persisted are ignored. Unknown keys follow unknown_policy.

pub fn clear_run_scoped(&self)

Clear all Run-scoped keys, preserving Thread-scoped keys.
