producer

Producing records, including the idempotent and transactional paths.

Every function is async

Including the ones that only read local state — which is not how they would be written for a native implementation. A host component plugin's capabilities are installed on a caller's linker as concurrent host functions, and a sync func fails to bind there with "type mismatch with async". One sync function is therefore enough to make the whole interface unservable from a component, and this package's host-plugin world describes exactly that deployment. An async lift costs a native implementation nothing — the body returns without suspending — so this is the version that both kinds of provider can serve.
