Trait Zero

pub trait Zero {
    // Required methods
    fn zero() -> Self;
    fn is_zero(&self) -> bool;
}

A trait pretty much similar to num_traits::Zero, but without the need of implementing Add.

Required Methods

fn zero() -> Self

Returns the zero value.

fn is_zero(&self) -> bool

Returns whether this value 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.
