# AnyUserIdentity A user identity that performs type erasure by wrapping another user identity. ``` struct AnyUserIdentity ``` ## Topics ### Creating a user identity [`init(T)`](/documentation/Assignables/AnyUserIdentity/init(_:)) Initializes this type eraser with a user identity to wrap. [`init(from: any Decoder) throws`](/documentation/Assignables/AnyUserIdentity/init(from:)) Creates a new instance by decoding from the given decoder. ### Setting the scope [`func scope(() throws -> R) rethrows -> R`](/documentation/Assignables/AnyUserIdentity/scope(_:)-1wfwz) Sets the user identity for document-related operations that occur within the closure passed in. [`func scope(() async throws -> R) async rethrows -> R`](/documentation/Assignables/AnyUserIdentity/scope(_:)-76dnq) Sets the user identity for document-related operations that occur within the async closure passed in. ### Inspecting an identity [`var stringRepresentation: String`](/documentation/Assignables/AnyUserIdentity/stringRepresentation) String representation of this user identity for display or debugging purposes. [`var typeID: String`](/documentation/Assignables/AnyUserIdentity/typeID) A unique type identifier for this user identity. [`enum Error`](/documentation/Assignables/AnyUserIdentity/Error) Error type for this user identity. ### Instance Methods [`func encode(to: any Encoder) throws`](/documentation/Assignables/AnyUserIdentity/encode(to:)) Encodes this value into the given encoder. [`func hash(into: inout Hasher)`](/documentation/Assignables/AnyUserIdentity/hash(into:)) Hashes the essential components of this value by feeding them into the given hasher. ### Comparing identities [`static func == (AnyUserIdentity, AnyUserIdentity) -> Bool`](/documentation/Assignables/AnyUserIdentity/==(_:_:)) Returns a Boolean value indicating whether two values are equal. ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Equatable`](/documentation/Swift/Equatable) [`Decodable`](/documentation/Swift/Decodable) [`Hashable`](/documentation/Swift/Hashable) [`Encodable`](/documentation/Swift/Encodable) [`UserIdentity`](/documentation/Assignables/UserIdentity) --- Copyright © 2026 Apple Inc.
