# Struct std::num::NonZeroU8 [−] [src]

    pub struct NonZeroU8(_);

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

An integer that is known not to equal zero.

This may enable some memory layout optimization such as:

    use std::mem::size_of;
    assert_eq!(size_of::<Option<std::num::NonZeroU32>>(), size_of::<u32>());Run

## Methods

### `impl NonZeroU8`
[src]

#### `pub const unsafe fn new_unchecked(n: u8) -> NonZeroU8`
[src]

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

Create a non-zero without checking the value.

# Safety

The value must not be zero.

#### `pub fn new(n: u8) -> Option<NonZeroU8>`
[src]

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

Create a non-zero if the given value is not zero.

#### `pub fn get(self) -> u8`
[src]

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

Returns the value as a primitive type.

## 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`)
