Trait IntegerLen 

pub trait IntegerLen {
    // Required method
    fn len(self) -> usize;
}

A trait IntegerLen to determine the number of digits of integers.

Usage

Basic use of the trait.

use num_convert::IntegerLen;

assert_eq!(i8::MAX.len(), 3usize);
assert_eq!(u128::MAX.len(), 39usize);

Examples

assert_eq!(0_i8.len(), 1_usize);
assert_eq!(i128::MAX.len(), 39_usize);

Required Methods

fn len(self) -> usize

Returns the number of digits for self value.
