Storage

Topics

Initializers

• init(logger: Logger)
  Create a new Storage container using the given logger.

Instance Methods

• func asyncShutdown() async
  For every key in the container having a shutdown closure, invoke the closure. Designed to be invoked during an explicit app shutdown process or in a reference type’s deinit.
• func clear()
  Delete all values from the container. Does not invoke shutdown closures.
• func contains<Key>(Key.Type) -> Bool
  Test whether the given key exists in the container.
• func get<Key>(Key.Type) -> Key.Value?
  Get the value of the given key if it exists and is of the proper type.
• func set<Key>(Key.Type, to: Key.Value?, onShutdown: ((Key.Value) throws -> ())?)
  Set or remove a value for a given key, optionally providing a shutdown closure for the value.
• func setWithAsyncShutdown<Key>(Key.Type, to: Key.Value?, onShutdown: ((Key.Value) async throws -> ())?) async
  Set or remove a value for a given key, optionally providing an async shutdown closure for the value.
• func shutdown()
  For every key in the container having a shutdown closure, invoke the closure. Designed to be invoked during an explicit app shutdown process or in a reference type’s deinit.

Subscripts

• subscript<Key>(Key.Type) -> Key.Value?
  Read/write access to values via keyed subscript.
• subscript<Key>(Key.Type, default _: @autoclosure () -> Key.Value) -> Key.Value
  Read access to a value via keyed subscript, adding the provided default value to the storage if the key does not already exist. Similar to Swift/Dictionary/subscript(key:default:). The defaultValue autoclosure is evaluated only when the key does not already exist in the container.
