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.
