# Trait core::nonzero::Zeroable [−] [src]

    pub unsafe trait Zeroable {
        fn is_zero(&self) -> bool;
    }

Deprecated since 1.26.0

: use `std::ptr::NonNull` or `std::num::NonZero*` instead

🔬 This is a nightly-only experimental API. (`nonzero` #49137)

deprecated

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
