The rules for parsing integers don't specify an upper bound on the value that can be returned, so the `parse_integer_digits` method can be used to check whether the given arbitrarily-large StringView is valid according to these rules. The `parse_integer` and `parse_non_negative_integer` methods would fail for values larger than 2147483647 when they shouldn't have.
