1.34.0[−][src]Struct std::num::NonZeroI8
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroI8>
is the same size as i8
:
use std::mem::size_of; assert_eq!(size_of::<Option<core::num::NonZeroI8>>(), size_of::<i8>());Run
Methods
impl NonZeroI8
[src]
pub const unsafe fn new_unchecked(n: i8) -> NonZeroI8
