And what's the public API/stdlib/bindings inside the WASM workers? I've been thinking a lot about this today and I think you might have a hidden gem here. Wher

  Ha, thanks! I'll ping you an email. > And what's the public API/stdlib/bindings inside the WASM workers? Wazero (via Extism) carries the load here. As it stands, the runtime lifts three basic host functions into guest code which enable the RPC-like behaviour, injection of caller-context and basic logging[1], which are in turn referenced in the guest code like in the example[2]. In the reverse direction, guest code exposes it's public APIs via build directives[3], which are handled by the runtime code[4]. Figured that concrete examples might be more helpful here (I hope the formatting works).
