Expand description
Everything a hayson language binding needs that is not about the foreign boundary itself: the
DatabaseError/TableError → envelope mapping, the JSON shapes of the engine’s result types,
the open() options document, and the predicate document Table::query takes.
Nothing here knows what it is bound to. The bindings that do — hayson-napi (Node native
addon) and hayson-wasm (wasm32-wasip1) — own their own handle bookkeeping and their own way
of raising an error, and share the whole of this crate.
