You can log things just like we do in Rob functions,
pass the LogLevel enum variant and then format your output like you’r
using the println! macro. For instance:
Special symbol that you can put at the end of your slice while passing it
to the append function to perform append and move acp ptr simultaneously.
But I recommend you to use the append_mv function instead, it does the same but,
you don’t need to put anything special at the end of the slice.
