What platform are you compiling on/for? Can I also get cargo --version

[LivacoNew]

Nvm, just ran into this on my phone while testing something for Android. I don't know much about pointer-land but I'm guessing this just different systems using different pointer types (aka signed/unsigned). Imagine that Rust probably has a built-in way to deal with this I just didn't know about .-.

[LivacoNew]

yep
