Enum GcTrigger 

pub enum GcTrigger {
    Threshold,
    EvalReturn,
    InterpreterDrop,
    NotebookCell,
    NotebookReset,
    AgentTurn,
    SchedulerIdle,
    Explicit,
}

Which safe point requested a collection pass. Purely observational — recorded on the GcPassEvent so telemetry can attribute collector work to the code path that triggered it; the pass itself runs identically for every trigger.

Variants

Threshold

Registry growth crossed the collection threshold at a candidate birth (make_closure or a data-cycle constructor).

EvalReturn

Top-level eval return (REPL line, script form, embedded eval).

InterpreterDrop

Interpreter teardown (Interpreter::drop).

NotebookCell

Notebook cell eval return.

NotebookReset

Notebook kernel reset mop-up.

AgentTurn

Agent tool-loop turn boundary.

SchedulerIdle

Cooperative scheduler went idle (all tasks done and reaped).

Explicit

Explicit request: (gc/collect), REPL ,gc, or a host call.
