# BNNSGraph.Shape

The specification of the shape of an argument.

## Declaration

```swift
struct Shape
```

## Overview

Overview The setDynamicShapes(_:forFunction:) function uses arrays of BNNSGraph.Shape structures as its input and output. This structure wraps the C API bnns_graph_shape_t type and derives its rank from the number of elements in the dimensions array.
