# usesInterfaceType(_:)

Checks if connections using the path may send traffic over a specific interface type.

## Declaration

```

## Discussion

Discussion Paths can use interface types by directly routing over an interface, routing through a tunnel that goes over a physical interface, or being eligble to use multiple interfaces directly.
