`#[repr(transparent)]pub struct NonZeroU128(u128);`

## 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>());
```

## 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);
```

1.53.0 (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);
```

🔬 This is a nightly-only experimental API. (`nonzero_ops`

`nonzero_ops`

)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.
