  ### [==(_:_:)](https://developers.home.google.com/reference/swift/GoogleHomeSDK/Structs/Reference#/s:13GoogleHomeSDK9ReferenceV2eeoiySbAC_ACtFZ)


  ` Returns a Boolean value indicating whether two values are equal.

  Equality is the inverse of inequality. For any values `a` and `b`,
  `a == b` implies that `a != b` is `false`.

  #### Declaration

  Swift

      static func == (lhs: Reference, rhs: Reference) -> Bool

  #### Parameters

  |---|---|
  | ` lhs ` | A value to compare. |
  | ` rhs ` | Another value to compare. |
