# LowLevelRenderer.RenderState

The per-frame render state passed to the render(using:_:) callback.

## Declaration

```swift
struct RenderState
```

## Overview

Overview RenderState is non-copyable and non-escapable; it is only valid for the duration of the render(using:_:) callback. Use its methods to encode individual draw calls, or access encoder to issue custom Metal commands between draws.
