Struct UpdateCoordinator 

pub struct UpdateCoordinator<'a> { /* private fields */ }

Coordinates provider, store, integrity, health and rollback boundaries.

Implementations

impl<'a> UpdateCoordinator<'a>

pub fn new( provider: &'a dyn UpdateProvider, store: &'a dyn ArtifactStore, health: &'a dyn ActivationHealthCheck, max_artifact_bytes: usize, ) -> UpdateResult<Self>

Creates a coordinator with an explicit artifact byte bound.

pub fn new_with_authenticity( provider: &'a dyn UpdateProvider, store: &'a dyn ArtifactStore, health: &'a dyn ActivationHealthCheck, authenticity: &'a dyn ArtifactAuthenticityVerifier, max_artifact_bytes: usize, ) -> UpdateResult<Self>

Creates a coordinator with an explicit artifact authenticity policy.

pub fn new_for_preparation( provider: &'a dyn UpdateProvider, store: &'a dyn ArtifactStore, authenticity: &'a dyn ArtifactAuthenticityVerifier, max_artifact_bytes: usize, ) -> UpdateResult<Self>

Creates a staging coordinator for process-level health verification.

pub fn apply( &self, request: &UpdateRequest, runtime_version: &str, protocol_version: &str, ) -> UpdateResult<UpdateOutcome>

Applies an update using the production no-fault path.

pub fn prepare( &self, request: &UpdateRequest, runtime_version: &str, protocol_version: &str, ) -> UpdateResult<UpdatePreparation>

Stages and activates an update without committing it.

An application parent uses this two-phase path when the candidate must be restarted and probed before ArtifactStore::commit or rollback.

pub fn stage_candidate( &self, request: &UpdateRequest, runtime_version: &str, protocol_version: &str, ) -> UpdateResult<UpdateStaging>

Verifies and stages a candidate without changing the active artifact.

pub fn apply_with_faults( &self, request: &UpdateRequest, runtime_version: &str, protocol_version: &str, faults: &dyn UpdateFaultInjector, ) -> UpdateResult<UpdateOutcome>

Applies an update while exposing deterministic lifecycle fault points.
