Support imported functions

[turbolent]

Does this library support importing Python functions into the WebAssembly module instances?

I couldn't find any example and looking at the code at https://github.com/wasmerio/python-ext-wasm/blob/89cecbbd672023f2b12ae183641fba2f9cc4c7e3/src/instance.rs#L133-L134 it seems like it is not supported yet?

Hi,

Not yet. We are working on it. The Wasmer runtime API, with its C and C++ bindings, support that but for statically typed languages. We have to make it compliant with dynamically typed languages.

@Hywan Is there any update? This is already supported in Go version of Wasmer library.

[Hywan]

It's easier in Go than it is with Python. I'm working on it at the runtime-core level, see wasmerio/wasmer#882. It's a WIP.

@Hywan Great! When do you expect to be finished?

[Hywan]

I can't specify any date :-).

Would like to see this feature. I'm trying to port a Rust module compiled with wasm_bindgen to run on Python but am getting "Failed to instantiate the module" errors since there are no function imports available.

[Hywan]

Yup, working on it :-).

Still going?

I only thought I needed the emscripten grow memory hook, there may be an alternative solution...

Yes, #140 is under review.
