# MTL4UpdateSparseTextureMappingOperation

Groups together arguments for an operation to update a sparse texture mapping.

## Declaration

```swift
struct MTL4UpdateSparseTextureMappingOperation
```

## Overview

Overview When performing a sparse mapping update, you are responsible for issuing a barrier against stage MTLStageResourceState. You can determine the sparse texture tier by calling sparseTextureTier.

## Topics

### Initializers
