Expand description

Operations on SIMD vectors of unsigned integers.

Required Associated Types

🔬This is a nightly-only experimental API. (portable_simd #86656)

Scalar type contained by this SIMD vector type.

Required Methods

🔬This is a nightly-only experimental API. (portable_simd #86656)

Lanewise saturating add.

Examples
use core::u32::MAX;
let x = Simd::from_array([2, 1, 0, MAX]);
let max = Simd::splat(MAX);
let unsat = x + max;
let sat = x.saturating_add(max);
assert_eq!(unsat, Simd::from_array([1, 0, MAX, MAX - 1]));
assert_eq!(sat, max);
Run

Lanewise saturating subtract.

Examples
use core::u32::MAX;
let x = Simd::from_array([2, 1, 0, MAX]);
let max = Simd::splat(MAX);
let unsat = x - max;
let sat = x.saturating_sub(max);
assert_eq!(unsat, Simd::from_array([3, 2, 1, 0]));
assert_eq!(sat, Simd::splat(0));
