# MTL4BufferRange

## Declaration

```swift
struct MTL4BufferRange
```

## Overview

Overview A struct representing a range of a Metal buffer. The offset into the buffer is included in the address. The length is generally optional, which a value of (uint64_t)-1 representing the range from the given address to the end of the buffer. However, providing the length can enable more accurate API validation, especially when sub-allocating ranges of a buffer.
