Struct RetainedPlan 

pub struct RetainedPlan { /* private fields */ }

What a store persists for a plan: the definition and its binding identity.

This is deliberately not a serialized plan. The lowered form is an index over the definition, it is rebuilt on load, and keeping a second compiled copy — on disk or anywhere else — would create a second authority that can drift from the definition it claims to describe.

Implementations

impl RetainedPlan

pub fn of( compiled: &CompiledWorkflow, key: PlanKey, ) -> Result<RetainedPlan, PlanMismatch>

Pair a lowered plan with the key it was lowered for.

The pair is checked against itself here, which is what makes it impossible to file a plan under a key that describes a different definition: a plan served under a key must be that key’s plan.

pub fn definition(&self) -> &WorkflowDefinition

pub fn key(&self) -> &PlanKey

pub fn binding_digest(&self, identity: &PlanIdentity) -> String

The identity a run stays bound to, whether the lowered form exists now or has to be rebuilt, digested under identity’s lines.

pub fn to_wire_bytes(&self) -> Result<Vec<u8>, PlanMismatch>

The canonical bytes a store persists.

pub fn retained_bytes(&self) -> Result<usize, PlanMismatch>

Bytes this plan charges a cache that retains it.

pub fn from_wire_bytes(bytes: &[u8]) -> Result<RetainedPlan, PlanMismatch>

Read back what a store persisted, checking the pair before accepting it so a drifted store cannot fabricate a binding identity.

pub fn rebuild( &self, supported_schema: &SchemaId, ) -> Result<CompiledWorkflow, WorkflowValidationFailure>

Rebuild the authority: lower the retained definition again.

Lowering is this build’s compiler, so the caller admits the key first: a key bound to compiler semantics this build does not implement is handed off rather than rebuilt here. supported_schema is the same host-bound schema identity the original lowering was admitted under.
