Struct WorkflowState 

pub struct WorkflowState { /* private fields */ }

Materialized view over the task-lifecycle log.

Serialize / Deserialize are derived so the state can be snapshotted via CortexAdapter::snapshot (the plan’s per-chain checkpoint that bounds failover replay) and restored via open_from_snapshot.

Implementations

impl WorkflowState

pub fn new() -> Self

Create an empty state.

pub fn get(&self, id: TaskId) -> Option<TaskState>

Look up a task’s state by id (TaskState is Copy).

pub fn len(&self) -> usize

Number of live tasks.

pub fn is_empty(&self) -> bool

True if no tasks are live.

pub fn contains(&self, id: TaskId) -> bool

True if a task with id is live.

pub fn all(&self) -> impl Iterator<Item = (TaskId, TaskState)> + '_

Iterate over every live (id, state).

pub fn in_status(&self, status: TaskStatus) -> impl Iterator<Item = TaskId> + '_

Iterate over the ids of tasks currently in status — the scheduler’s “what’s runnable / waiting / blocked” read.

pub fn is_cancel_requested(&self, id: TaskId) -> bool

Has cancellation been requested for id? The single-writer worker polls this and drives the task to a terminal status.

pub fn cancel_requested_count(&self) -> usize

Number of tasks with a pending cancel request.

pub fn children_of(&self, id: TaskId) -> &[TaskId]

Direct children (shards / spawned children) of id.

pub fn parent_of(&self, id: TaskId) -> Option<TaskId>

The parent of id, if it was linked under one.

pub fn descendants(&self, id: TaskId) -> Vec<TaskId>

Every transitive descendant of id (children, grandchildren, …), excluding id itself. The set a delete cascades over; the caller also uses it to prune triggers waiting on the subtree. Deterministic order (BFS).

pub fn subtree(&self, id: TaskId) -> Vec<TaskId>

id plus all its descendants — the full subtree a delete removes.

pub fn status_counts(&self) -> StatusCounts

Roll-up of task counts per status (observability summary).

Trait Implementations

impl Clone for WorkflowState

fn clone(&self) -> WorkflowState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WorkflowState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for WorkflowState

fn default() -> WorkflowState
