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

    #[lang = "non_zero"]
    pub struct NonZero<T: Zeroable>(_);

Deprecated since 1.26.0

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

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

deprecated

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>`

[src]

####

`pub const unsafe fn new_unchecked(inner: T) -> Self`

[src]

Deprecated since 1.26.0

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

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

deprecated

[src]

Deprecated since 1.26.0

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

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

deprecated

Creates an instance of NonZero with the provided value.

####

`pub fn get(self) -> T`

[src]

Deprecated since 1.26.0

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

## 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`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
