SafetyLocationElement

public struct SafetyLocationElement : HorizonElement

HorizonElement that contains data about a safety location.

To receive such elements in the HorizonSnapshot, specify HorizonElementType.safetyLocationType in the HorizonOptions that you register with the HorizonEngine:

let horizonOptions = HorizonOptions(
    id: UUID(),
    elementTypes: [.safetyLocationType],
    ...
)
