Struct std::num::Wrapping1.0.0[−][src]

#[repr(transparent)]
pub struct Wrapping<T>(pub T);
Expand description

Provides intentionally-wrapped arithmetic on T.

Operations like + on u32 values are intended to never overflow, and in some debug configurations overflow is detected and results in a panic. While most arithmetic falls into this category, some code explicitly expects and relies upon modular arithmetic (e.g., hashing).

Wrapping arithmetic can be achieved either through methods like wrapping_add, or through the Wrapping<T> type, which says that all standard arithmetic operations on the underlying value are intended to have wrapping semantics.

The underlying value can be retrieved through the .0 index of the Wrapping tuple.

Examples

use std::num::Wrapping;

let zero = Wrapping(0u32);
let one = Wrapping(1u32);

assert_eq!(u32::MAX, (zero - one).0);
Run

Examples

Basic usage:

#![feature(wrapping_int_impl)]
use std::num::Wrapping;

assert!(Wrapping(16u128).is_power_of_two());
assert!(!Wrapping(10u128).is_power_of_two());
Run
🔬 This is a nightly-only experimental API. (wrapping_next_power_of_two #32463)

needs decision on wrapping behaviour

Returns the smallest power of two greater than or equal to self.

When return value overflows (i.e., self > (1 << (N-1)) for type uN), overflows to 2^N = 0.

Examples

Basic usage:

#![feature(wrapping_next_power_of_two)]
use std::num::Wrapping;

assert_eq!(Wrapping(2u128).next_power_of_two(), Wrapping(2));
assert_eq!(Wrapping(3u128).next_power_of_two(), Wrapping(4));
assert_eq!(Wrapping(200_u8).next_power_of_two(), Wrapping(0));
