#[repr(transparent)]pub struct NonZeroI32(_);
An integer that is known not to equal zero.
This enables some memory layout optimization. For example, Option<NonZeroI32> is the same size as i32:
use std::mem::size_of; assert_eq!(size_of::<Option<core::num::NonZeroI32>>(), size_of::<i32>());
impl NonZeroI32[src]
pub const unsafe fn new_unchecked(n: i32) -> NonZeroI32[src]
Creates a non-zero without checking the value.
The value must not be zero.
pub const fn new(n: i32) -> Option<NonZeroI32>[src]
Creates a non-zero if the given value is not zero.
pub const fn get(self) -> i32[src]
Returns the value as a primitive type.
