changes needed to compile against rustler v0.35.0

LGTM

Mind that Clippy is yelling at you because I think you have to either let _ = the resource expressions in lib.rs or explicitly match them if you wanna implement a different logic.

@fabriziosestito one tiny recap before I go to sleep.

I tried to drop _build before running the tests and it works. My theory is that restoring the prebuilt dependencies and compiled code prevents the actual Rust code to be built, especially the dylib .so library that is needed by some of the tests. Dropping _build is a caveman way of triggering the rebuild of just everything.

This is a very naive approach and I absolutely don't like it. 😄

@dottorblaster I removed the commit you added and now somehow the tests are passing. There was something wrong with the GH cache.
