# SIMDStorage

A type that can function as storage for a SIMD vector type.

## Declaration

```swift
protocol SIMDStorage
```

## Overview

Overview The SIMDStorage protocol defines a storage layout and provides elementwise accesses. Computational operations are defined on the SIMD protocol, which refines this protocol, and on the concrete types that conform to SIMD.
