#86656)## Expand description

Portable SIMD module.

This module offers a portable abstraction for SIMD operations that is not bound to any particular hardware architecture.

## Modules

- preludeExperimentalThe portable SIMD prelude.

## Macros

- simd_swizzleExperimentalConstructs a new SIMD vector by copying elements from selected lanes in other vectors.

## Structs

- LaneCountExperimentalSpecifies the number of lanes in a SIMD vector as a type.
- MaskExperimentalA SIMD vector mask for
`LANES`

elements of width specified by`Element`

. - SimdExperimentalA SIMD vector with the shape of
`[T; N]`

but the operations of`T`

.

## Enums

- WhichExperimentalSpecifies a lane index into one of two SIMD vectors.

## Traits

`Simd::cast`
