Trait ConstZero 

pub trait ConstZero: Sized {
    const ZERO: Self;
}

Defines an associated constant representing the additive identity element for Self.

This is a pure constant-carrier: it requires only that Self has a compile-time 0, not that it implements Zero (and hence not Add). Keeping it decoupled lets capability-restricted types — e.g. a constant-time integer with bit ops but no arithmetic — supply the 0 constant that PrimBits needs without being forced to implement addition. Numeric types still implement both.

Required Associated Constants

const ZERO: Self

The additive identity element of Self, 0.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
