Structure

Extend

A wrapper around a simple [String: Any] storage dictionary used to implement Extendable.

struct Extend

Overview

final cass MyType: Extendable { ... }
extension MyType {
    var foo: Int {
        get { return extend.get(\MyType.foo, default: 0) }
        set { extend.set(\MyType.foo, to: newValue) }
    }
}

Note

Extend conforms to Codable, but will yield an empty dictionary. Extensions are used for convenience and should not be encoded or decoded.

Topics

Initializers

init()
Create a new extend.
init(dictionaryLiteral: (String, Any)...)
See ExpressibleByDictionaryLiteral.
init(from: any Decoder) throws
See Codable.

Instance Properties

var storage: [String : Any]
The internal storage.

Instance Methods

func encode(to: any Encoder) throws
See Codable.
func get(_:default:)
Gets a value from the Extend storage falling back to the default value if it does not exist or cannot be casted to T.
func set(_:to:)
Set a value to the Extend storage.

Subscripts

subscript(String) -> Any?
Allow subscripting by String key. This is a type-erased alternative to the get(_:default:) and set(:to:) methods.
