Function what_to_execute

pub fn what_to_execute(
    version: u128,
    arg: &String,
    command_nicknames: &[&str],
    all_is_255: bool,
) -> Option<usize>

Decides what to execute Version must == 0 or == 1 Behaviour for version not being == 0 or == 1 is undefined When it is executed it returns a number that is determined by comparing arg to command nicknames (capital insensitive) and if arg is in command nicknames it returns Some(i) where i == the index that it is at Else if all_is_255 && arg == “all” than Some(255) is returned Else if arg is a decimal integer it returns arg as a integer Else it returns None if version == 0 or Some(245) if version == 1

asserteq!(Some(1),command_ifyer::what_to_execute(0,"1",&["hi","HeLlo"],false));
