Primary LanguageRust

Shows broken code generation for async static factories.

Run yarn build to produce errors.

Relevant Generated Chunks

Async factory:

napi::bindgen_prelude::execute_tokio_future(
    env,
    async move { Ok(MyNumber::future_4().await) },
    move |env, _ret| {
        _args_ref.drop(env);
        cb.factory("future4", _ret)
    },
)

Fails to compile because cb is not Send. CallbackInfo::factory requires an env (provided in this callback), but also a this, which is not currently threaded through.

Returning a result:

napi::bindgen_prelude::execute_tokio_future(
    env,
    async move { MyNumber::maybe_future_4().await },
    move |env, _ret| {
        _args_ref.drop(env);
        cb.factory("maybeFuture4", _ret?)
    },
)

Fails to compile because execute_tokio_future does a layer of Result unwrapping, meaning that _ret is now the value contained in Ok, and is no longer a Result, so the ? does not apply.
