Is it possible to call async functions? If yes how?

[weezy20]

I am using a rust crate that requires the use of async functions, and so my main function looks like this:

#[neon::main]
fn main(mut cx: ModuleContext) -> NeonResult<()> {
    cx.export_function("async_fn", async_fn)?;
    Ok(())
}

I would like to .await on the async_fn, what is the way to achieve this?

There is a proposal to simplify, but it currently requires some boilerplate.

See the tokio-fetch example for more details.

If it's acceptable to block the JavaScript main thread while awaiting, it can be significantly simplified by using block_on to synchronously block until the Future completes.

For testing, I would like to use block_on for the time being just to make sure it actually works. How do you suggest I write this though?

I suggest trying the tokio-fetch example. Let me know if you have any questions.
