  ` Creates a new Trait instance using data read from the given `TraitDecoder`.
  Throws
  `HomeError.parseError` when parsing fails.

  #### Declaration

  Swift

      init(decoder: TraitDecoder, interactionProxy: (any InteractionProxy)?, metadata: TraitMetadata) throws

  #### Parameters

  |---|---|
  | ` decoder ` | The raw data representing this Trait. |

  ### [encode(with:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Google/GroupMembershipTrait#/s:15GoogleHomeTypes0A0O20GroupMembershipTraitV6encode4withy0aB3SDK0F7EncoderC_tKF)


  ` Writes this object to the given `TraitEncoder`.
  Throws `HomeError.encodingFailed` if the data could not be encoded.

  ### [==(_:_:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Google/GroupMembershipTrait#/s:15GoogleHomeTypes0A0O20GroupMembershipTraitV2eeoiySbAE_AEtFZ)


  ` 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: https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Google.html.GroupMembershipTrait, rhs: https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Google.html.GroupMembershipTrait) -> Bool

  #### Parameters

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

  ### [hash(into:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Google/GroupMembershipTrait#/s:15GoogleHomeTypes0A0O20GroupMembershipTraitV4hash4intoys6HasherVz_tF)


  ` Hashes the essential components of this value by feeding them into the
  given hasher.

  Implement this method to conform to the `Hashable` protocol. The
  components used for hashing must be the same as the components compared
  in your type's `==` operator implementation. Call `hasher.combine(_:)`
  with each of these components.
  Important

  In your implementation of `hash(into:)`,
  don't call `finalize()` on the `hasher` instance provided,
  or replace it with a different instance.
  Doing so may become a compile-time error in the future.

  #### Declaration

  Swift

      func hash(into hasher: inout Hasher)
