Convert string to u128

For the other direction, you can use the format!() macro (Rust Playground): fn main() { let diff_str = "0x000fffffffffffffffffffffffffffff".to_string(); let diff_digits = diff_str.strip_prefix("0x").unwrap(); let diff = u128::from_str_radix(diff_digits, 16).unwrap(); let diff_bytes = diff.to_le_bytes(); let de_diff_bytes = diff_bytes; let de_diff = u128::from_le_bytes(de_diff_bytes); let de_diff_str = format!("0x{de_diff:032x}"); assert_eq!(diff_str, de_diff_st…
