Trait Zeroable 

pub unsafe trait Zeroable: Sized {
    // Provided method
    fn zeroed() -> Self { ... }
}

Trait for types that can be safely created with zeroed.

An all-zeroes value may or may not be the same value as the Default value of the type.

Safety

• Your type must be inhabited (eg: no Infallible).
• Your type must be allowed to be an “all zeroes” bit pattern (eg: no NonNull<T>).

Features

Some impls are feature gated due to the MSRV policy:

• MaybeUninit<T> was not available in 1.34.0, but is available under the zeroable_maybe_uninit feature flag.
• Atomic* types require Rust 1.60.0 or later to work on certain platforms, but is available under the zeroable_atomics feature flag.
• [T; N] for arbitrary N requires the min_const_generics feature flag.

Provided Methods

fn zeroed() -> Self

Calls zeroed.

This is a trait method so that you can write MyType::zeroed() in your code. It is a contract of this trait that if you implement it on your type you must not override this method.

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.
