# Struct core::nonzero::NonZero [−] [src]

    pub struct NonZero<T: Zeroable>(_);

Unstable (`nonzero` #27730)

: needs an RFC to flesh out the design

A wrapper type for raw pointers and integers that will never be NULL or 0 that might allow certain optimizations.

## Methods

### `impl<T: Zeroable> NonZero<T>`

#### `const unsafe fn new(inner: T) -> NonZero<T>`

Unstable (`nonzero` #27730)

: needs an RFC to flesh out the design

Creates an instance of NonZero with the provided value. You must indeed ensure that the value is actually "non-zero".

## 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`)
