1.28.0[][src]Struct std::num::NonZeroU8

pub struct NonZeroU8(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroU8> is the same size as u8:

use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU8>>(), size_of::<u8>());Run


impl NonZeroU8[src]

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

Creates a non-zero without checking the value.


The value must not be zero.

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

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

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

Returns the value as a primitive type.
