Implementations§

Source§

impl<T: SimdElement, const N: usize> Simd<T, N>

Source

pub(crate) const ZERO: Self

A value of this type where all elements are zeroed out.

Source

pub(crate) const fn from_array(elements: [T; N]) -> Self

Source

pub(crate) const fn splat(value: T) -> Self

Source

pub(crate) const fn extract_dyn(&self, index: usize) -> T

Extract the element at position index. Note that index is not a constant so this operation is not efficient on most platforms. Use for testing only.
