Trait Num

pub trait Num:
    Sized
    + Copy
    + AddAssign
    + SubAssign
    + Ord
    + Sub<Output = Self>
    + Neg<Output = Self>
    + Eq
    + Add<Output = Self> {
    const ZERO: Self;
    const ONE: Self;
    const TWO: Self;

    // Required methods
    fn iter_range(range: Range<Self>) -> impl Iterator<Item = Self>;
    fn as_u64(self) -> u64;
}

A helper trait for specifying generic numeric types.

Required Associated Constants

const ZERO: Self

The neutral value for addition and subtraction.

const ONE: Self

The neutral value for multiplication and division.

const TWO: Self

For when you can’t use + in const contexts, but need a 2

Required Methods

fn iter_range(range: Range<Self>) -> impl Iterator<Item = Self>

Iterate over a range. Workaround to std::ops::Range’s Iterator impl not being implementable for custom types.

fn as_u64(self) -> u64

Convert the value to a u64. Used for seeding random number generators from coordinates.

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.

Implementations on Foreign Types
