Struct std::num::NonZeroU8

1.28.0 · source · [−]

#[repr(transparent)]
pub struct NonZeroU8(_);

Expand description

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, Option<NonZeroU8> is the same size as u8:

use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU8>>(), size_of::<u8>());

Implementations

source

impl NonZeroU8

const: 1.28.0 · source

pub const unsafe fn new_unchecked(n: u8) -> NonZeroU8

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: u8) -> Option<NonZeroU8>

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

const: 1.34.0 · source

pub const fn get(self) -> u8

Returns the value as a primitive type.

pub const fn checked_add(self, other: u8) -> Option<NonZeroU8>

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

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.

pub const fn saturating_add(self, other: u8) -> NonZeroU8

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

Add an unsigned integer to a non-zero value. Return u8::MAX on overflow.

pub const unsafe fn unchecked_add(self, other: u8) -> NonZeroU8

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

Add an unsigned integer to a non-zero value, 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 > u8::MAX.

Examples

#![feature(nonzero_ops)]

let one = NonZeroU8::new(1)?;
let two = NonZeroU8::new(2)?;

assert_eq!(two, unsafe { one.unchecked_add(1) });

Run

source

pub const fn checked_next_power_of_two(self) -> Option<NonZeroU8>

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

Returns the smallest power of two greater than or equal to n. Check for overflow and return None if the next power of two is greater than the type’s maximum value. As a consequence, the result cannot wrap to zero.

Examples

#![feature(nonzero_ops)]

let two = NonZeroU8::new(2)?;
let three = NonZeroU8::new(3)?;
let four = NonZeroU8::new(4)?;
let max = NonZeroU8::new(u8::MAX)?;

assert_eq!(Some(two), two.checked_next_power_of_two() );
assert_eq!(Some(four), three.checked_next_power_of_two() );
assert_eq!(None, max.checked_next_power_of_two() );

source

pub const fn log2(self) -> u32

🔬 This is a nightly-only experimental API. (int_log #70887)

Returns the base 2 logarithm of the number, rounded down.

This is the same operation as u8::log2, except that it has no failure cases to worry about since this value can never be zero.

Examples

#![feature(int_log)]

assert_eq!(NonZeroU8::new(7).unwrap().log2(), 2);
assert_eq!(NonZeroU8::new(8).unwrap().log2(), 3);
assert_eq!(NonZeroU8::new(9).unwrap().log2(), 3);

Run

source

pub const fn log10(self) -> u32

🔬 This is a nightly-only experimental API. (int_log #70887)

Returns the base 10 logarithm of the number, rounded down.

This is the same operation as u8::log10, except that it has no failure cases to worry about since this value can never be zero.

Examples

#![feature(int_log)]

assert_eq!(NonZeroU8::new(99).unwrap().log10(), 1);
assert_eq!(NonZeroU8::new(100).unwrap().log10(), 2);
assert_eq!(NonZeroU8::new(101).unwrap().log10(), 2);

pub const fn checked_mul(self, other: NonZeroU8) -> Option<NonZeroU8>

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

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 = NonZeroU8::new(2)?;
let four = NonZeroU8::new(4)?;
let max = NonZeroU8::new(u8::MAX)?;

assert_eq!(Some(four), two.checked_mul(two));
assert_eq!(None, max.checked_mul(two));

pub const fn saturating_mul(self, other: NonZeroU8) -> NonZeroU8

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

Examples

#![feature(nonzero_ops)]

let two = NonZeroU8::new(2)?;
let four = NonZeroU8::new(4)?;
let max = NonZeroU8::new(u8::MAX)?;

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

Run

source

pub const unsafe fn unchecked_mul(self, other: NonZeroU8) -> NonZeroU8

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

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 > u8::MAX.

Examples

pub const fn checked_pow(self, other: u32) -> Option<NonZeroU8>

🔬 This is a nightly-only experimental API. (nonzero_ops #84186)

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 = NonZeroU8::new(3)?;
let twenty_seven = NonZeroU8::new(27)?;
let half_max = NonZeroU8::new(u8::MAX / 2)?;

Examples

impl NonZeroU8

1.59.0 · source

pub const fn is_power_of_two(self) -> bool

Returns true if and only if self == (1 << k) for some k.

On many architectures, this function can perform better than is_power_of_two() on the underlying integer type, as special handling of zero can be avoided.

Examples

Basic usage:

let eight = std::num::NonZeroU8::new(8).unwrap();
assert!(eight.is_power_of_two());
let ten = std::num::NonZeroU8::new(10).unwrap();
assert!(!ten.is_power_of_two());
