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