Trait atoi::MaxNumDigits

pub trait MaxNumDigits {
    fn max_num_digits(radix: Self) -> usize;
    fn max_num_digits_negative(radix: Self) -> usize;
}

A bounded integer, whose representation can overflow and therefore can only store a maximum number of digits

Required methods

fn max_num_digits(radix: Self) -> usize

Given a representation with a radix character I, what is the maximum number of digits we can parse without the integer overflowing for sure?

fn max_num_digits_negative(radix: Self) -> usize

Returns the maximum number of digits a negative representation of I can have depending on radix.
