Trait ToDigits

pub trait ToDigits
where
    Self: Copy + Clone + Num + NumCast + DivAssign,
{
    // Provided method
    fn to_digits(&self) -> Vec<i8> { ... }
}

Provided Methods

fn to_digits(&self) -> Vec<i8>

Converts integer to Vec<i8> of its digits (base 10).

Example

Basic usage:

use num_digitize::ToDigits;

let number: u8 = 12;
let vector: Vec<i8> = vec![1, 2];
assert_eq!(number.to_digits(), vector);

Negative numbers return all the digits negative Vec<u8>:

use num_digitize::ToDigits;
let number = -12;
assert_eq!(number.to_digits(), vec![-1, -2]);

Reason for this is mathematically you can easily add these back to the original number like so:

-123 -> [-1, -2, -3]
(-1 * 10^2) + (-2 * 10^1) + (-3 * 10^0) = -123

Or with FromDigits trait.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
