Trait ZeroableThing 

pub trait ZeroableThing: Sized {
    const ZERO: Self;

    // Required method
    fn is_zero(&self) -> bool;
}

Describes a trait for some types that are valid when passed as a zero

mainly for usage with ShouldNotBeZero

Required Associated Constants

const ZERO: Self

Required Methods

fn is_zero(&self) -> bool

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.
