Struct sp_std::num::NonZeroI8

1.34.0 · source ·
pub struct NonZeroI8(_);
Expand description

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroI8> is the same size as i8:

use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroI8>>(), size_of::<i8>());

Layout

NonZeroI8 is guaranteed to have the same layout and bit validity as i8 with the exception that 0 is not a valid instance. Option<NonZeroI8> is guaranteed to be compatible with i8, including in FFI.

Implementations§

source§

impl NonZeroI8

const: 1.34.0 · source

pub const unsafe fn new_unchecked(n: i8) -> NonZeroI8

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: i8) -> Option<NonZeroI8>

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

const: 1.34.0 · source

pub const fn get(self) -> i8

Returns the value as a primitive type.

source§

impl NonZeroI8

1.53.0 (const: 1.53.0) · source

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::NonZeroI8::new(-1i8).unwrap();

assert_eq!(n.leading_zeros(), 0);
1.53.0 (const: 1.53.0) · source

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::NonZeroI8::new(0b0101000).unwrap();

assert_eq!(n.trailing_zeros(), 3);

assert_eq!(pos_five.overflowing_neg(), (neg_five, false));
assert_eq!(min.overflowing_neg(), (min, true));
source

pub const fn saturating_neg(self) -> NonZeroI8

🔬This is a nightly-only experimental API. (nonzero_negation_ops)

Example
#![feature(nonzero_negation_ops)]

let pos_five = NonZeroI8::new(5)?;

impl NonZeroI8

1.64.0 (const: 1.64.0) · source

pub const fn checked_mul(self, other: NonZeroI8) -> Option<NonZeroI8>

Multiplies two non-zero integers together. Checks for overflow and returns None on overflow. As a consequence, the result cannot wrap to zero.

Examples
let two = NonZeroI8::new(2)?;
let four = NonZeroI8::new(4)?;
let max = NonZeroI8::new(i8::MAX)?;

assert_eq!(Some(four), two.checked_mul(two));
assert_eq!(None, max.checked_mul(two));
1.64.0 (const: 1.64.0) · source

pub const fn saturating_mul(self, other: NonZeroI8) -> NonZeroI8

Multiplies two non-zero integers together. Return i8::MAX on overflow.

Examples
let two = NonZeroI8::new(2)?;
let four = NonZeroI8::new(4)?;
let max = NonZeroI8::new(i8::MAX)?;

assert_eq!(four, two.saturating_mul(two));
assert_eq!(max, four.saturating_mul(max));
source

pub const unsafe fn unchecked_mul(self, other: NonZeroI8) -> NonZeroI8

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

Multiplies 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 > i8::MAX, or self * rhs < i8::MIN.

Examples
#![feature(nonzero_ops)]

let two = NonZeroI8::new(2)?;
let four = NonZeroI8::new(4)?;

assert_eq!(four, unsafe { two.unchecked_mul(two) });
1.64.0 (const: 1.64.0) · source

pub const fn checked_pow(self, other: u32) -> Option<NonZeroI8>

Raises non-zero value to an integer power. Checks for overflow and returns None on overflow. As a consequence, the result cannot wrap to zero.

Examples
let three = NonZeroI8::new(3)?;
let twenty_seven = NonZeroI8::new(27)?;
let half_max = NonZeroI8::new(i8::MAX / 2)?;

assert_eq!(Some(twenty_seven), three.checked_pow(3));
assert_eq!(None, half_max.checked_pow(3));
1.64.0 (const: 1.64.0) · source

pub const fn saturating_pow(self, other: u32) -> NonZeroI8

Raise non-zero value to an integer power. Return i8::MIN or i8::MAX on overflow.

Examples
let three = NonZeroI8::new(3)?;
let twenty_seven = NonZeroI8::new(27)?;
let max = NonZeroI8::new(i8::MAX)?;

assert_eq!(twenty_seven, three.saturating_pow(3));

impl NonZeroI8

1.70.0 · source

pub const MIN: NonZeroI8 = Self::new(i8::MIN).unwrap()

The smallest value that can be represented by this non-zero integer type, equal to i8::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!(NonZeroI8::MIN.get(), i8::MIN);
1.70.0 · source

pub const MAX: NonZeroI8 = Self::new(i8::MAX).unwrap()

The largest value that can be represented by this non-zero integer type, equal to i8::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.
