If not feasible to implement a functionality in Motoko, is it possible to create a Motoko interface able to call an existing library?

Is this paragraph saying that I can basically use any Rust library as long as this library is not attempting to use the file system?

The file system is one example. I don’t know if there’s a comprehensive list of what does/doesn’t work but it seems there may be an opportunity to create a resource that does so.

@ildefons

is there any other constraint?

Below is another limitation, at least for now. I thought this might interest you as well.

Wasm module defined ___ globals which exceeds the maximum number allowed 200

When deploying my wasm, I am getting this error: The invocation to the wallet call forward method failed with the error: An error happened during the call: 5: Wasm module of canister xxxxx-xxxxx-xxxxx-xxxxx-xxx is not valid: Wasm module defined 220 globals which exceeds the maximum number allowed 200. What do these globals refer to ? I am trying to figure out where they come from, so I can fix my code. I am using C++, and I linked in a 3rd party json library that triggered this error.
