# Struct std::num::NonZeroU128

1.28.0 · source · [−]`#[repr(transparent)]pub struct NonZeroU128(_);`

## Expand description

An integer that is known not to equal zero.

This enables some memory layout optimization.
For example, `Option<NonZeroU128>`

is the same size as `u128`

:

```
use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU128>>(), size_of::<u128>());
```

Run## Implementations

source### impl NonZeroU128

### impl NonZeroU128

const: 1.28.0 · source#### pub const unsafe fn new_unchecked(n: u128) -> NonZeroU128

#### pub const unsafe fn new_unchecked(n: u128) -> NonZeroU128

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: u128) -> Option<NonZeroU128>

#### pub const fn new(n: u128) -> Option<NonZeroU128>

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

### impl NonZeroU128

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::NonZeroU128::new(u128::MAX).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::NonZeroU128::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);
```

source#### pub const fn checked_add(self, other: u128) -> Option<NonZeroU128>

#### pub const fn checked_add(self, other: u128) -> Option<NonZeroU128>

Add an unsigned integer to a non-zero value.
Check for overflow and return `None`

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

##### Examples

```
#![feature(nonzero_ops)]
let one = NonZeroU128::new(1)?;
let two = NonZeroU128::new(2)?;
let max = NonZeroU128::new(u128::MAX)?;
assert_eq!(Some(two), one.checked_add(1));
assert_eq!(None, max.checked_add(1));
```

source#### pub const unsafe fn unchecked_add(self, other: u128) -> NonZeroU128

#### pub const unsafe fn unchecked_add(self, other: u128) -> NonZeroU128

Add an unsigned integer to a non-zero value,
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 > u128::MAX`

.

##### Examples

```
#![feature(nonzero_ops)]
let one = NonZeroU128::new(1)?;
let two = NonZeroU128::new(2)?;
assert_eq!(two, unsafe { one.unchecked_add(1) });
```

Runsource#### pub const fn checked_next_power_of_two(self) -> Option<NonZeroU128>

#### pub const fn checked_next_power_of_two(self) -> Option<NonZeroU128>

Returns the smallest power of two greater than or equal to n.
Check for overflow and return `None`

if the next power of two is greater than the type’s maximum value.
As a consequence, the result cannot wrap to zero.

##### Examples

```
#![feature(nonzero_ops)]
let two = NonZeroU128::new(2)?;
let three = NonZeroU128::new(3)?;
let four = NonZeroU128::new(4)?;
let max = NonZeroU128::new(u128::MAX)?;
assert_eq!(Some(two), two.checked_next_power_of_two() );
assert_eq!(Some(four), three.checked_next_power_of_two() );
assert_eq!(None, max.checked_next_power_of_two() );
```

Runsource#### pub const fn log2(self) -> u32

#### pub const fn log2(self) -> u32

Returns the base 2 logarithm of the number, rounded down.

This is the same operation as
`u128::log2`

,
except that it has no failure cases to worry about
since this value can never be zero.

##### Examples

```
#![feature(int_log)]
assert_eq!(NonZeroU128::new(7).unwrap().log2(), 2);
assert_eq!(NonZeroU128::new(8).unwrap().log2(), 3);
assert_eq!(NonZeroU128::new(9).unwrap().log2(), 3);
```

Runsource#### pub const fn log10(self) -> u32

Returns the base 10 logarithm of the number, rounded down.

This is the same operation as

,
except that it has no failure cases to worry about
since this value can never be zero.

##### Examples

```
#![feature(int_log)]
assert_eq!(NonZeroU128::new(99).unwrap().log10(), 1);
assert_eq!(NonZeroU128::new(100).unwrap().log10(), 2);

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

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

##### Examples
