Trait HasZero

pub trait HasZero {
    // Required method
    fn zero() -> Self;
}

A trait for types which have a zero value.

Functions may assume the following:

• x = x + zero() = zero() + x

Required Methods

fn zero() -> Self

Returns the zero value for the type.

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.
