Hi @Niceural! I reproduced your error. Apparently bool_to_option was stabilized in rustc 1.62. If that's an option for you, just update your compiler to that version and everything should work just fine!

hi @manuelmauro . I opted for a more radical solution: switch to an arch based distribution. I seem to have installed a more recent version of rustc by doing that (1.65.0). thanks a lot for your help!
