# canAddEdge(_:)

Returns whether the given edge can be added to the graph.

## Declaration

```swift
func canAddEdge(_ edge: ComputeNodeGraph.Edge) -> Bool
```

## Parameters

- `edge`: The edge to test.

## Return Value

Return Value true if calling addEdge(_:) with this edge would succeed.

## Discussion

Discussion This is the non-throwing preflight check for addEdge(_:). Use it to validate a connection — for example, to highlight compatible ports during drag-and-drop — without modifying the graph.
