Struct InstanceViewStore 

pub struct InstanceViewStore { /* private fields */ }

Exact explicit namespace retained across construction, close and save retry.

Implementations

impl InstanceViewStore

pub fn new( profile_state_root: PathBuf, device_id: &str, workspace_id: &str, ) -> Result<InstanceViewStore, ThawError>

Views stored under a local profile directory.

Errors

Rejects a relative profile root or empty/control-character identities.

pub fn with_store( store: Rc<dyn DurableStore>, device_id: &str, workspace_id: &str, ) -> Result<InstanceViewStore, ThawError>

Views stored through a host-provided store.

Errors

Rejects empty/control-character identities.

pub fn portable( cache: PortableStorage, workspace: &str, ) -> Result<InstanceViewStore, ThawError>

Use the same explicit profile/device cache as the record owner.

pub fn without_persistence(self) -> InstanceViewStore

A model-only service keeps presentation ephemeral while retaining the original profile/device/workspace binding. It never reads or replaces a user’s saved window view. Record persistence is unaffected.

pub fn load( &self, instance_id: u64, ) -> Result<Option<SavedInstanceView>, ThawError>

Errors

Reports I/O, malformed/versioned envelopes, invalid geometry and foreign bindings. Invalid source bytes are never repaired or replaced.

pub fn save(&self, instance: &SavedInstanceView) -> Result<(), ThawError>

Errors

Refuses invalid/foreign envelopes before replacing the stored View, and reports a replacement the store failed to commit. A store waiting on its host to commit is not a failure.
