Struct MemoryPersistence 

pub struct MemoryPersistence;

In-memory SchedulerPersistence backend. Always returns an empty load_all; every other call is a no-op.

Used by tests and as the default backend when the host has not yet wired a durable backend (e.g., during early Uni::build before the storage manager is available).

Trait Implementations

impl Debug for MemoryPersistence

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MemoryPersistence

fn default() -> MemoryPersistence

Returns the “default value” for a type.

impl SchedulerPersistence for MemoryPersistence

fn record_started( &self, _id: &QName, _started_at: SystemTime, ) -> Result<(), SchedulerPersistenceError>

Persist a job’s transition into a new run.

fn record_finished( &self, _id: &QName, _finished_at: SystemTime, _success: bool, ) -> Result<(), SchedulerPersistenceError>

Persist the outcome of a finished run.

fn cancel(&self, _id: &QName) -> Result<(), SchedulerPersistenceError>

Persist a cancellation.

fn load_all(&self) -> Result<Vec<SchedulerJobRecord>, SchedulerPersistenceError>

Reload all known job records (used on host startup to restore scheduler state across restart). Order is unspecified — the driver re-registers them in any order.

fn record_scheduled( &self, _id: &QName, _schedule: &Schedule, ) -> Result<(), SchedulerPersistenceError>

Persist a job’s schedule at registration time.

fn flush_checkpoint(&self) -> Result<(), SchedulerPersistenceError>

Force any in-memory buffers to durable storage.
