1.28.0[−][src]Struct core::num::NonZeroU32
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroU32> is the same size as u32:
use std::mem::size_of; assert_eq!(size_of::<Option<std::num::NonZeroU32>>(), size_of::<u32>());Run
Methods
impl NonZeroU32[src]
impl NonZeroU32pub const unsafe fn new_unchecked(n: u32) -> Self[src]
pub const unsafe fn new_unchecked(n: u32) -> Selfpub fn new(n: u32) -> Option<Self>[src]
pub fn new(n: u32) -> Option<Self>Create a non-zero if the given value is not zero.
pub fn get(self) -> u32[src]
pub fn get(self) -> u32Returns the value as a primitive type.
