Struct ExecutionCheckpoint 

pub struct ExecutionCheckpoint {
    pub workflow_id: WorkflowId,
    pub completed_task_ids: Vec<TaskId>,
    pub variables: HashMap<String, Value>,
    pub timestamp_secs: u64,
}

Serializable checkpoint for pause/resume of workflow execution.

This struct captures the minimal state needed to resume a paused workflow: the set of already-completed task IDs and the current execution context variables. It can be persisted to disk, a database, or transferred over the network, then passed back to WorkflowExecutor::resume_from_checkpoint.

Fields

workflow_id: WorkflowId

Workflow identifier.

completed_task_ids: Vec<TaskId>

Task IDs that had completed at the time the checkpoint was taken.

variables: HashMap<String, Value>

Execution context variables at checkpoint time.

timestamp_secs: u64

Unix timestamp (seconds) when the checkpoint was captured.

Implementations

impl ExecutionCheckpoint

pub fn to_json(&self) -> Result<String>

Serialize the checkpoint to a compact JSON string.

Errors

Returns a WorkflowError if JSON serialization fails.

pub fn from_json(json: &str) -> Result<Self>

Deserialize a checkpoint from a JSON string.

Errors

Returns a WorkflowError if JSON parsing fails.
