Full storage interface expected from thingd engine adapters.

Provided Methods

fn search_rebuild_required(&self) -> bool

Return whether the adapter has an asynchronous derived search rebuild that should be progressed by the hosting runtime.

fn search_rebuild_step(&mut self, _batch_size: usize) -> ThingdResult<bool>

Process one bounded asynchronous search rebuild batch.

Errors

Returns a storage error when the adapter cannot advance the rebuild.

fn retry_search_rebuild(&mut self) -> bool

Retry a degraded search rebuild when bounded recovery permits another generation.

fn search_rebuild_status(&self) -> Option<SearchRebuildStatus>

Available on crate feature persistent only.

Return backend-specific asynchronous search rebuild status, when supported.

fn storage_maintenance_status(&self) -> StorageMaintenanceStatus

Return backend-specific storage maintenance state.

fn compact_storage(&mut self) -> ThingdResult<()>

Compact the primary durable store when supported.

Errors

Returns an error when the backend cannot persist or compact its data.

fn storage_diagnostics(&self) -> ThingdResult<StorageDiagnostics>

Return bounded storage diagnostics. Adapters may add backend-specific details through their own APIs without changing this stable summary.

Errors

Returns an error when the backing store cannot read its counts.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
