Operations on SIMD vectors of unsigned integers.
Required Associated Types§
sourcetype Scalar
🔬This is a nightly-only experimental API. (portable_simd)
type Scalar
portable_simd)Scalar type contained by this SIMD vector type.
sourcetype Cast<T: SimdElement>
🔬This is a nightly-only experimental API. (portable_simd)
type Cast<T: SimdElement>
portable_simd)A SIMD vector with a different element type.
Required Methods§
sourcefn cast<T>(self) -> Self::Cast<T>where
T: SimdCast,
🔬This is a nightly-only experimental API. (portable_simd)
fn cast<T>(self) -> Self::Cast<T>where
T: SimdCast,
portable_simd)Performs elementwise conversion of this vector’s elements to another SIMD-valid type.
This follows the semantics of Rust’s as conversion for casting integers (wrapping to
other integer types, and saturating to float types).
sourcefn wrapping_neg(self) -> Self
🔬This is a nightly-only experimental API. (portable_simd)
fn wrapping_neg(self) -> Self
portable_simd)Wrapping negation.
Like u32::wrapping_neg, all applications of this function will wrap, with the exception
of -0.
sourcefn saturating_add(self, second: Self) -> Self
🔬This is a nightly-only experimental API. (portable_simd)
fn saturating_add(self, second: Self) -> Self
portable_simd)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);sourcefn saturating_sub(self, second: Self) -> Self
🔬This is a nightly-only experimental API. (portable_simd)
fn saturating_sub(self, second: Self) -> Self
portable_simd)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));sourcefn reduce_sum(self) -> Self::Scalar
🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_sum(self) -> Self::Scalar
portable_simd)Returns the sum of the elements of the vector, with wrapping addition.

🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_product(self) -> Self::Scalar
portable_simd)Returns the product of the elements of the vector, with wrapping multiplication.
sourcefn reduce_max(self) -> Self::Scalar
🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_max(self) -> Self::Scalar
portable_simd)Returns the maximum element in the vector.
sourcefn reduce_min(self) -> Self::Scalar
🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_min(self) -> Self::Scalar
portable_simd)Returns the minimum element in the vector.
sourcefn reduce_and(self) -> Self::Scalar
🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_and(self) -> Self::Scalar

🔬This is a nightly-only experimental API. (portable_simd)
fn reduce_or(self) -> Self::Scalar
portable_simd)Returns the cumulative bitwise “or” across the elements of the vector.

sourcefn reverse_bits(self) -> Self
🔬This is a nightly-only experimental API. (portable_simd)
fn reverse_bits(self) -> Self
portable_simd)Reverses the order of bits in each elemnent. The least significant bit becomes the most significant bit, second least-significant bit becomes second most-significant bit, etc.
