Trait ConstInit 

pub trait ConstInit {
    const INIT: Self;
}

🌱 A trait for giving a type a useful const-friendly initial value.

---

^{📍 code}

---

Comparison with Default

Default represents the type’s natural baseline, usually a neutral or zero-like state. ConstInit simply provides a valid const-time initializer, without requiring that meaning.

When a type has a clear Default, these traits should return the same value to keep behavior consistent. They only diverge for types that cannot offer a safe or meaningful Default, but still need a guaranteed const initializer.

• Use Default for semantic baselines.
• Use ConstInit for invariant-safe const initialization.

Required Associated Constants

const INIT: Self

Returns the compile-time “initial value” for a type.

Dyn Compatibility

This trait is not dyn compatible.

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