Trait Num 

pub trait Num:
    Copy
    + PartialEq
    + Debug
    + Add<Output = Self>
    + Sub<Output = Self>
    + Mul<Output = Self> {
    // Required methods
    fn zero() -> Self;
    fn one() -> Self;
    fn from_i64(v: i64) -> Self;
}

Foundation: anything that can add, subtract, multiply, and has 0/1.

Required Methods

fn zero() -> Self

Additive identity.

fn one() -> Self

Multiplicative identity.

fn from_i64(v: i64) -> Self

Convert from a signed integer (lossy for floats below 2^53).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
