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>());
RunImplementations
sourceimpl NonZeroI128
impl NonZeroI128
const: 1.34.0 · sourcepub 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 · sourcepub 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.

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::NonZeroI128::new(-1i128).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::NonZeroI128::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);

sourcepub 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)?;

sourcepub 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)?;

Runsourcepub const fn checked_pow(self, other: u32) -> Option<NonZeroI128>
pub const fn checked_pow(self, other: u32) -> Option<NonZeroI128>
Raise non-zero value to an integer power.
Check for overflow and return None
on overflow.
As a consequence, the result cannot wrap to zero.
Examples
#![feature(nonzero_ops)]
let three = NonZeroI128::new(3)?;
let twenty_seven = NonZeroI128::new(27)?;
let half_max = NonZeroI128::new(i128::MAX / 2)?;

Runsourcepub 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.
Return i128::MIN
or i128::MAX
on overflow.
Examples
#![feature(nonzero_ops)]
let three = NonZeroI128::new(3)?;
let twenty_seven = NonZeroI128::new(27)?;
let max = NonZeroI128::new(i128::MAX)?;

impl NonZeroI128
sourcepub 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.

assert_eq!(NonZeroI128::MIN.get(), i128::MIN);
Runsourcepub const MAX: NonZeroI128 = Self::new(i128::MAX).unwrap()

The largest value that can be represented by this non-zero
integer type,
equal to i128::MAX
.
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.
