# AccelerateMutableBuffer

A type that represents a mutable buffer.

## Declaration

```swift
protocol AccelerateMutableBuffer<Element> : AccelerateBuffer
```

## Overview

Overview If you implement your own type that conforms to AccelerateMutableBuffer and uses the default implementation of withUnsafeMutableBufferPointer(_:), your type needs to return a nonnil result from withContiguousMutableStorageIfAvailable(_:).
