tsoutsman opened issue #4415:

Loading in a Component hits this unimplemented!() statement when the component was generated with wit-bindgen and wit-component. According to @alexcrichton this is a bug.

Test Case

I've created a repo. To recreate the example run ./run.sh.

Expected Results

The component loads.

Actual Results

Panic.

To explain my original confusion, this is an unimplemented! macro for type exports, not type imports, which makes more sense.
