Base trait for every SIMD types.

Required Associated Types§

source

type Element: SimdValue<Element = Self::Element, SimdBool = bool>

The type of the elements of each lane of this SIMD value.

source

type SimdBool: SimdBool

Type of the result of comparing two SIMD values like self.

Required Methods§

source

fn lanes() -> usize

The number of lanes of this SIMD value.

source

fn splat(val: Self::Element) -> Self

Initializes an SIMD value with each lanes set to val.

source

fn extract(&self, i: usize) -> Self::Element

Extracts the i-th lane of self.

Panics if i >= Self::lanes().

source

unsafe fn extract_unchecked(&self, i: usize) -> Self::Element

Extracts the i-th lane of self without bound-checking.

source

fn replace(&mut self, i: usize, val: Self::Element)

Replaces the i-th lane of self by val.

Panics if i >= Self::lanes().

source

unsafe fn replace_unchecked(&mut self, i: usize, val: Self::Element)

Replaces the i-th lane of self by val without bound-checking.

source

fn select(self, cond: Self::SimdBool, other: Self) -> Self

Merges self and other depending on the lanes of cond.

For each lane of cond with bits set to 1, the result’s will contain the value of the lane of self. For each lane of cond with bits set to 0, the result’s will contain the value of the lane of other.

Provided Methods§

source

fn map_lanes(self, f: impl Fn(Self::Element) -> Self::Element) -> Self
where Self: Clone,

Applies a function to each lane of self.

Note that, while convenient, this method can be extremely slow as this requires to extract each lane of self and then combine them again into a new SIMD value.

source

fn zip_map_lanes( self, b: Self, f: impl Fn(Self::Element, Self::Element) -> Self::Element ) -> Self
where Self: Clone,

Applies a function to each lane of self paired with the corresponding lane of b.

Note that, while convenient, this method can be extremely slow as this requires to extract each lane of self and then combine them again into a new SIMD value.

Object Safety§

This trait is not object safe.
