I was hitting the same error messages as others have shown here. I think the example project (this? GitHub - rusterlium/NifIo: Rustler example. Implements file IO in a NIF. · GitHub) hasn’t been updated for the latest rustler version.
@mickel8 thanks for the example code, I was able to make some solid progress working forward from this.
I’m working on a table data structure for time-series analysis, and I have the basic parts working in rust, so now I’m working thru the integration process with elixir. If it helps anyone, you can see my code here.

After line 115 I have the rustler parts, all it does currently is instantiate structs that hold a mutable float, and there’s functions for update, read, and add. I had to keep things simple at first. Next I’ll be figuring out how to make this work with my SlidingWindow data structure.
