Struct PersistentExecutor 

pub struct PersistentExecutor { /* private fields */ }

Authenticated persistent queue session over one immutable artifact identity.

Implementations

impl PersistentExecutor

pub fn from_bytes( registration: &'static BackendRegistration, envelope_bytes: &[u8], initial: ResidentQueueState, ) -> Result<Self, ArtifactSessionError>

Authenticate and materialize an artifact envelope, then initialize retained queue state.

pub fn artifact(&self) -> Result<Digest, ArtifactSessionError>

Neutral artifact identity preserved across every queue update and recovery.

pub fn device(&self) -> Result<DeviceIdentity, ArtifactSessionError>

Current acquired device generation.

pub fn submit_and_wait( &self, state: ResidentQueueState, ) -> Result<ResidentQueueCompletion, ArtifactSessionError>

Replace the host queue mirror, submit once, and return the updated retained state.

pub fn recover( &self, failure: BackendError, ) -> Result<DeviceIdentity, ArtifactSessionError>

Rematerialize authenticated bytes after a structured device-loss failure.

Errors

Returns the original backend failure for every non-device-loss class.
