# Struct std::num::NonZeroI128

1.34.0 · source · [−]`#[repr(transparent)]pub struct NonZeroI128(_);`

## Expand description

An integer that is known not to equal zero.

This enables some memory layout optimization.
For example, `Option<NonZeroI128>`

is the same size as `i128`

:

```
use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroI128>>(), size_of::<i128>());
```

Run## Implementations

source### impl NonZeroI128

### impl NonZeroI128

const: 1.34.0 · source#### pub const unsafe fn new_unchecked(n: i128) -> NonZeroI128

#### pub const unsafe fn new_unchecked(n: i128) -> NonZeroI128

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 · source#### pub const fn new(n: i128) -> Option<NonZeroI128>

#### pub const fn new(n: i128) -> Option<NonZeroI128>

Creates a non-zero if the given value is not zero.

### impl NonZeroI128

1.53.0 (const: 1.53.0) · source#### pub 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::NonZeroI128::new(-1i128).unwrap();
assert_eq!(n.leading_zeros(), 0);
```

Run1.53.0 (const: 1.53.0) · source#### pub 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::NonZeroI128::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);
```

source#### pub const fn checked_mul(self, other: NonZeroI128) -> Option<NonZeroI128>

#### pub const fn checked_mul(self, other: NonZeroI128) -> Option<NonZeroI128>

Multiply two non-zero integers together.
Check for overflow and return `None`

on overflow.
As a consequence, the result cannot wrap to zero.

##### Examples

```
#![feature(nonzero_ops)]
let two = NonZeroI128::new(2)?;
let four = NonZeroI128::new(4)?;
let max = NonZeroI128::new(i128::MAX)?;

source#### pub const unsafe fn unchecked_mul(self, other: NonZeroI128) -> NonZeroI128

#### pub const unsafe fn unchecked_mul(self, other: NonZeroI128) -> NonZeroI128

Multiply two non-zero integers together,
assuming overflow cannot occur.
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
`self * rhs > i128::MAX`

, or `self * rhs < i128::MIN`

.

##### Examples

```
#![feature(nonzero_ops)]
let two = NonZeroI128::new(2)?;
let four = NonZeroI128::new(4)?;

##### Examples

```
#![feature(nonzero_ops)]
let three = NonZeroI128::new(3)?;
let twenty_seven = NonZeroI128::new(27)?;
let half_max = NonZeroI128::new(i128::MAX / 2)?;

assert_eq!(None, half_max.checked_pow(3));
```

Runsource#### pub const fn saturating_pow(self, other: u32) -> NonZeroI128

#### pub const fn saturating_pow(self, other: u32) -> NonZeroI128

Raise non-zero value to an integer power.

### impl NonZeroI128

source#### pub const MIN: NonZeroI128 = Self::new(i128::MIN).unwrap()

#### pub const MIN: NonZeroI128 = Self::new(i128::MIN).unwrap()

The smallest value that can be represented by this non-zero
integer type,
equal to `i128::MIN`

.

Note: While most integer types are defined for every whole
number between `MIN`

and `MAX`

, signed non-zero integers are
a special case. They have a “gap” at 0.

integer type,
equal to `i128::MAX`

.

Note: While most integer types are defined for every whole
