#[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.
use std::num::Wrapping;
let zero = Wrapping(0u32);
let one = Wrapping(1u32);
assert_eq!(u32::MAX, (zero - one).0);
RunWrapping<T> is guaranteed to have the same layout and ABI as T.
