# Struct gstd::prelude::num::NonZeroI128

1.34.0 · source · `pub struct NonZeroI128(/* private fields */);`

## 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>());
```

## §Layout

`NonZeroI128`

is guaranteed to have the same layout and bit validity as `i128`

with the exception that `0`

is not a valid instance.
`Option<NonZeroI128>`

is guaranteed to be compatible with `i128`

,
including in FFI.

Thanks to the null pointer optimization,
`NonZeroI128`

and `Option<NonZeroI128>`

are guaranteed to have the same size and alignment:

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

## 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.

source#### pub unsafe fn from_mut_unchecked(n: &mut i128) -> &mut NonZeroI128

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

)

#### pub unsafe fn from_mut_unchecked(n: &mut i128) -> &mut NonZeroI128

`nonzero_from_mut`

)Converts a primitive mutable reference to a non-zero mutable reference
without checking whether the referenced value is non-zero.
This results in undefined behavior if `*n`

is zero.

1.53.0 (const: 1.53.0) · source#### pub const fn leading_zeros(self) -> u32

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

```
let n = std::num::NonZeroI128::new(-1i128).unwrap();
assert_eq!(n.leading_zeros(), 0);
```

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);
```
