-
-/// Trait for types that can be safely created with
-/// [`zeroed`](core::mem::zeroed).
-///
-/// An all-zeroes value may or may not be the same value as the
-/// [Default](core::default::Default) value of the type.
-///
-/// ## Safety
-///
-/// * Your type must be inhabited (eg: no
-/// [Infallible](core::convert::Infallible)).
-/// * Your type must be allowed to be an "all zeroes" bit pattern (eg: no
-/// [`NonNull<T>`](core::ptr::NonNull)).
-///
-/// ## Features
-///
-/// Some `impl`s 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.
