Struct std::num::NonZeroI32
1.34.0 · source · [−]#[repr(transparent)]pub struct NonZeroI32(_);
Expand description
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>());
RunImplementations
sourceimpl NonZeroI32
impl NonZeroI32
const: 1.34.0 · sourcepub const unsafe fn new_unchecked(n: i32) -> NonZeroI32
pub const unsafe fn new_unchecked(n: i32) -> NonZeroI32
Creates a non-zero without checking whether the value is non-zero. This results in undefined behaviour if the value is zero.
Safety
The value must not be zero.
const: 1.47.0 · sourcepub const fn new(n: i32) -> Option<NonZeroI32>
pub const fn new(n: i32) -> Option<NonZeroI32>
Creates a non-zero if the given value is not zero.

1.53.0 (const: 1.53.0) · sourcepub const fn leading_zeros(self) -> u32
pub const fn leading_zeros(self) -> u32
Returns the number of leading zeros in the binary representation of self
.
On many architectures, this function can perform better than leading_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroI32::new(-1i32).unwrap();
assert_eq!(n.leading_zeros(), 0);
Run1.53.0 (const: 1.53.0) · sourcepub const fn trailing_zeros(self) -> u32
pub const fn trailing_zeros(self) -> u32
Returns the number of trailing zeros in the binary representation
of self
.
On many architectures, this function can perform better than trailing_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroI32::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);

Multiplies two non-zero integers together.
Checks for overflow and returns None
on overflow.
As a consequence, the result cannot wrap to zero.

Overflow is unchecked, and it is undefined behaviour to overflow
even if the result would wrap to a non-zero value.
The behaviour is undefined as soon as

, or self * rhs < i32::MIN
