Struct std::num::NonZeroI32  
1.34.0 · source · [−]#[repr(transparent)]pub struct NonZeroI32(_);Expand description
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroI32> is the same size as i32:
use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroI32>>(), size_of::<i32>());Implementations
sourceimpl NonZeroI32
 
impl NonZeroI32
const: 1.34.0 · sourcepub const unsafe fn new_unchecked(n: i32) -> NonZeroI32
 
pub const unsafe fn new_unchecked(n: i32) -> NonZeroI32
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: i32) -> Option<NonZeroI32>
 
pub const fn new(n: i32) -> Option<NonZeroI32>
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::NonZeroI32::new(-1i32).unwrap();
assert_eq!(n.leading_zeros(), 0);1.53.0 (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::NonZeroI32::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);sourceimpl NonZeroI32

pub const fn abs(self) -> NonZeroI32

Computes the absolute value of self,
with overflow information, see

assert_eq!((min, true), min.overflowing_abs());sourcepub const fn saturating_abs(self) -> NonZeroI32
 
pub const fn saturating_abs(self) -> NonZeroI32
Saturating absolute value, see
i32::saturating_abs.
Example
#![feature(nonzero_ops)]
let pos = NonZeroI32::new(1)?;
let neg = NonZeroI32::new(-1)?;
let min = NonZeroI32::new(i32::MIN)?;
let min_plus = NonZeroI32::new(i32::MIN + 1)?;

sourcepub const fn checked_mul(self, other: NonZeroI32) -> Option<NonZeroI32>
 
pub const fn checked_mul(self, other: NonZeroI32) -> Option<NonZeroI32>
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 = NonZeroI32::new(2)?;
let four = NonZeroI32::new(4)?;
let max = NonZeroI32::new(i32::MAX)?;
assert_eq!(Some(four), two.checked_mul(two));

pub const fn saturating_mul(self, other: NonZeroI32) -> NonZeroI32
sourcepub const unsafe fn unchecked_mul(self, other: NonZeroI32) -> NonZeroI32
 
pub const unsafe fn unchecked_mul(self, other: NonZeroI32) -> NonZeroI32
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 > i32::MAX, or self * rhs < i32::MIN.
Examples
#![feature(nonzero_ops)]
let two = NonZeroI32::new(2)?;
let four = NonZeroI32::new(4)?;
assert_eq!(four, unsafe { two.unchecked_mul(two) });sourcepub const fn checked_pow(self, other: u32) -> Option<NonZeroI32>
 
pub const fn checked_pow(self, other: u32) -> Option<NonZeroI32>
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 = NonZeroI32::new(3)?;
let twenty_seven = NonZeroI32::new(27)?;
let half_max = NonZeroI32::new(i32::MAX / 2)?;
assert_eq!(Some(twenty_seven), three.checked_pow(3));
assert_eq!(None, half_max.checked_pow(3));sourcepub const fn saturating_pow(self, other: u32) -> NonZeroI32
 
pub const fn saturating_pow(self, other: u32) -> NonZeroI32
Raise non-zero value to an integer power.
Return i32::MIN or i32::MAX on overflow.
Examples
#![feature(nonzero_ops)]
let three = NonZeroI32::new(3)?;
let twenty_seven = NonZeroI32::new(27)?;
let max = NonZeroI32::new(i32::MAX)?;
assert_eq!(twenty_seven, three.saturating_pow(3));
