Enum DepTerminal 

pub enum DepTerminal {
    Complete,
    Error(Rc<str>),
}

A dep’s terminal state, visible to the fn via Ctx::terminal (R-deps-terminal / C-15). None ⇔ the dep is live; Some(..) ⇔ it COMPLETEd or ERRORed. Read by terminalAsRealInput operators (rescue/reduce/*Map) that treat an inner terminal as a real input rather than an absorbed settle.

Error carries the dep’s error message (an Rc<str>), not the original GraphError: Box<dyn Error> is not Clone, and a message crosses a dep subscription as a borrow (&Message), so the concrete error type cannot be preserved into this per-wave-cloneable record. Per-language (D24, D31 error=unknown — the top type); the message survives, the downcast does not.

Variants

Complete

The dep emitted COMPLETE.

Error(Rc<str>)

The dep emitted ERROR; carries its Display message (see type doc).
