1.34.0[][src]Struct std::num::NonZeroI32

#[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>());Run

Methods

impl NonZeroI32[src]

pub const unsafe fn new_unchecked(n: i32) -> NonZeroI32[src]

Creates a non-zero without checking the value.

Safety

The value must not be zero.

pub 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.
