# ComputeNodeGraph.StateType

The shape of a value stored in a compute graph’s state.

## Declaration

```swift
enum StateType
```

## Overview

Overview StateType describes what kind of value a state holds. The shape determines the slot’s size, alignment, and how it is surfaced in generated Metal source and in graph serialization.
