#[repr(transparent)]pub struct 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>());
impl NonZeroI8[src]
pub const unsafe fn new_unchecked(n: i8) -> NonZeroI8[src]
Creates a non-zero without checking the value.
The value must not be zero.
pub const fn new(n: i8) -> Option<NonZeroI8>[src]
Creates a non-zero if the given value is not zero.
pub const fn get(self) -> i8[src]
Returns the value as a primitive type.
