Struct Managed Execution Store &nbsp; Copy item path

pub fn get( &self, execution_id: &ExecutionId, ) -> ManagedExecutionStoreResult<Option<BoxRecord>>

Return one managed record without mutating or reconciling state.

pub fn get_by_operation_id( &self, operation_id: &OperationId, ) -> ManagedExecutionStoreResult<Option<BoxRecord>>

Return the record reserved by an idempotent creation operation.

pub fn reserve( &self, record: BoxRecord, ) -> ManagedExecutionStoreResult<ManagedExecutionReservation>

Atomically reserve one creation operation before backend side effects.

Retrying the same operation with the same full request returns the existing record. Reusing an operation ID for different creation intent fails without changing durable state.

pub fn transition( &self, execution_id: &ExecutionId, expected_generation: ExecutionGeneration, expected_state: ManagedExecutionState, next_state: ManagedExecutionState, ) -> ManagedExecutionStoreResult<BoxRecord>

Atomically compare generation and state, then persist one legal edge.

Completing pause and resume, and advancing a restart from teardown to startup, increments the runtime generation exactly once. Other edges retain the current generation.

pub fn transition_with( &self, execution_id: &ExecutionId, expected_generation: ExecutionGeneration, expected_state: ManagedExecutionState, next_state: ManagedExecutionState, update: impl FnOnce(&mut BoxRecord), ) -> ManagedExecutionStoreResult<BoxRecord>

Persist one legal transition and update runtime evidence in the same transaction.
