pub fn ref_value(slots: &[u64]) -> &ValueExpand description
The value a Ref2 pair at the head of slots holds by reference:
the one-element slice a JSON, extension, or handle producer
published (jit_boundary.md, axiom S7: one dereference).
The slots must hold a pair a producer published into storage that
is alive: its own scratch, an extern’s stored value, or a boundary
value alive for the call (axioms S3, S4). A pair of length zero,
an unset extern, reads as Value::None.
