#[repr(transparent)]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>());
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 const 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.
