Struct WorkflowCheckpoint 

pub struct WorkflowCheckpoint {
    pub workflow_id: String,
    pub completed_steps: Vec<String>,
    pub step_outputs: HashMap<String, Value>,
    pub created_at: u64,
    pub workflow_version: u32,
}

A snapshot of workflow execution state persisted to disk.

Fields

workflow_id: String

Unique identifier of the workflow this checkpoint belongs to.

completed_steps: Vec<String>

Names of steps that had completed when this checkpoint was taken.

step_outputs: HashMap<String, Value>

Arbitrary JSON outputs produced by each completed step, keyed by step name.

created_at: u64

Unix timestamp (seconds) when the checkpoint was created.

workflow_version: u32

Schema / content version of the workflow definition at checkpoint time.

Implementations

impl WorkflowCheckpoint

pub fn new(workflow_id: impl Into<String>, workflow_version: u32) -> Self

Creates a new checkpoint with the current wall-clock timestamp.

pub fn mark_step_completed( &mut self, step_name: impl Into<String>, output: Option<Value>, )

Marks a step as completed, optionally recording its output.

pub fn is_step_completed(&self, step_name: &str) -> bool

Returns true if the given step was already completed.

pub fn step_output(&self, step_name: &str) -> Option<&Value>

Returns the output for a completed step, if any was recorded.

pub fn completed_count(&self) -> usize

Returns the number of completed steps.
