char to_digit: avoid unnecessary casts to u64 Hello, in the `char::to_digit` method there are a few `as u64` casts that are not strictly necessary. I assume that the reason behind these casts is to avoid possible overflows in the `+ 10` add. This PR removes the aforementioned casts, avoiding the overflow issue by slightly modifying the ASCII letter to int mapping. Thanks, Happy new year. |
