Error importing rust crate

[jgall]

🐛 bug report

Importing Rust code by doing import {my_fun} from 'my_rust.rs is working fine for me, however, when I try to import a crate I've written via import {my_fun} from './my_crate/src/lib.rs' as seen here the build works however, in the javascript console in Firefox I get the following error:

TypeError: second argument must be an object

🎛 Configuration (.babelrc, package.json, cli command)

configuration and project visible at https://github.com/jgall/parcel_issue

🤔 Expected Behavior

The function should be imported properly.

😯 Current Behavior

I get an error in the console instead of loading a function from Rust.

💻 Code Sample

I wrote up a quick example that shows the bug (at least on my laptop it reproduces 100% of the time)

In chrome :

Uncaught (in promise) TypeError: WebAssembly.instantiate(): Imports argument must be present and must be an object

On Firefox
it fails on WebAssembly.instantiateStreaming(res); in node_src/builtins/loaders/browser/wasm-loader.js

Edit: wasm_bindgen seems to be unsuported #647
