Struct WorkflowTaskState 

pub struct WorkflowTaskState { /* private fields */ }

Task-local workflow scope: the run stack plus the per-task active-step attribution. Installed on the owning task’s TaskContextHandle (traced), inherited clone-shared by spawned children.

Trait Implementations

impl Default for WorkflowTaskState

fn default() -> Self

Returns the “default value” for a type.

impl TaskLocalValue for WorkflowTaskState

fn inherit(&self) -> Rc<dyn TaskLocalValue>

A spawned child clone-shares the run stack (each Rc<WorkflowCtx> is shared, so the child journals into the SAME run) and copies the spawner’s active-step attribution, but inherited scopes reset to token: None (the child cannot tear down an ancestor’s scope) and it mints from a fresh counter.

fn as_any(&self) -> &dyn Any

fn preflight_error(&self) -> Option<SemaError>

A task-local extension may fail a task before its next VM quantum. This is for shared fail-closed state (for example, a workflow child invalidating its owner), not ordinary language-level cancellation.

impl Trace for WorkflowTaskState
