Trait Zero

pub trait Zero {
    // Required methods
    fn zero() -> Self;
    fn is_zero(x: &Self) -> Choice;
}

Type that has zero value (additive identity)

Required Methods

fn zero() -> Self

Constructs zero value of Self

fn is_zero(x: &Self) -> Choice

Checks (in constant-time) if x is zero

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.
