A trait for types that may be used as SIMD vector elements.

Required Associated Constants

const VECTOR_LEN: usize

Capacity of Vector

Required Associated Types

type Vector: Sized + Copy

raw SIMD vector type like __m256i

Required Methods

fn is_available() -> bool

Returns these SIMD functions are available.

unsafe fn load(src: *const Self) -> Self::Vector

Loads values to raw SIMD vector.

Safety

Make sure Self::is_available() returns true and length of src is not less than Self::VECTOR_LEN.

unsafe fn load_partial(src: *const Self, len: usize) -> Self::Vector

Loads values to raw SIMD vector.

Safety

Make sure Self::is_available() returns true and length of src is not less than len.

unsafe fn store(dst: *mut Self, src: Self::Vector)

Stores raw SIMD vector to dst.

Safety

Make sure Self::is_available() returns true and capacity of dst is not less than Self::VECTOR_LEN.

unsafe fn store_partial(dst: *mut Self, src: Self::Vector, len: usize)

Stores raw SIMD vector to dst.

Safety

Make sure Self::is_available() returns true and capacity of dst is not less than len.

unsafe fn set(value: Self) -> Self::Vector

Creates a raw SIMD vector filled with value.

Safety

Make sure Self::is_available() returns true.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
