How to call from workers/rs ?

[joeblew999]

Is there a decent way to call this from workers-rs ?

The Sandbox SDK exposes a JavaScript API, so from workers-rs you'll need to bridge through wasm-bindgen / js-sys.

Minimal approach using the worker crate:

use wasm_bindgen::prelude::*;
use js_sys::{Function, Promise};
use wasm_bindgen_futures::JsFuture;
use worker::*;

#[wasm_bindgen]
extern C {
    #[wasm_bindgen(js_namespace = ["Aigur", "Sandbox"])]
    fn create(config: JsValue) -> Promise;
}

#[event(fetch)]
pub async fn main(req: Request, env: Env, _ctx: Context) -> Result<Response> {
    let sandbox = JsFuture::from(create(JsValue::NULL)).await?;
    // use the sandbox instance
    Ok(Response::ok("done")?)
}

Key points:

• worker crate v0.4+ works alongside wasm-bindgen
• Sandbox JS globals need #[wasm_bindgen] extern declarations
• Async SDK methods return Promise → convert with JsFuture::from().await

For wrangler.toml, if the Sandbox requires a service binding, call it via env.sandbox.fetch() in the worker crate. If you share which specific method you're trying to call, I can give a more targeted example.
