1.28.0[−][src]Struct std::num::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
Methods
impl NonZeroU8[src]
pub const unsafe fn new_unchecked(n: u8) -> NonZeroU8[src]
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.
