Enum TaskState 

pub enum TaskState {
    Submitted,
    Working,
    InputRequired,
    Completed,
    Failed,
    Cancelled,
}

The lifecycle state of a Task.

Legal flow: Submitted -> Working -> InputRequired -> Working -> Completed with Failed/Cancelled reachable from any non-terminal state.

Variants

Submitted

Accepted into the system, not yet picked up.

Working

Actively being worked by an engine.

InputRequired

Blocked awaiting human/agent input.

Completed

Finished successfully (terminal).

Failed

Finished unsuccessfully (terminal).

Cancelled

Aborted before completion (terminal).

Implementations

impl TaskState

pub fn is_terminal(self) -> bool

Returns true if no further transitions are legal from this state.

pub fn can_transition(from: TaskState, to: TaskState) -> bool

Pure transition predicate for the lifecycle FSM.

Terminal states have no outgoing edges. Non-terminal states may always move to Failed or Cancelled. The happy-path edges are explicit.
