Required Associated Types§
Required Methods§
fn extract(&self, i: usize) -> Self::Element
fn extract(&self, i: usize) -> Self::Element
Extracts the i-th lane of self.
Panics if i >= Self::lanes().
unsafe fn extract_unchecked(&self, i: usize) -> Self::Element
unsafe fn extract_unchecked(&self, i: usize) -> Self::Element
Extracts the i-th lane of self without bound-checking.
fn replace(&mut self, i: usize, val: Self::Element)
fn replace(&mut self, i: usize, val: Self::Element)
Replaces the i-th lane of self by val.
Panics if i >= Self::lanes().
unsafe fn replace_unchecked(&mut self, i: usize, val: Self::Element)
unsafe fn replace_unchecked(&mut self, i: usize, val: Self::Element)
Replaces the i-th lane of self by val without bound-checking.
fn select(self, cond: Self::SimdBool, other: Self) -> Self
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§
fn map_lanes(self, f: impl Fn(Self::Element) -> Self::Element) -> Selfwhere
Self: Clone,
fn map_lanes(self, f: impl Fn(Self::Element) -> Self::Element) -> Selfwhere 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.
fn zip_map_lanes(
self,
b: Self,
f: impl Fn(Self::Element, Self::Element) -> Self::Element
) -> Selfwhere
Self: Clone,
fn zip_map_lanes( self, b: Self, f: impl Fn(Self::Element, Self::Element) -> Self::Element ) -> Selfwhere 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.
