Enumerations

A kind of database event. See the TransactionObserver protocol for more information.

DatabaseDateEncodingStrategy specifies how EncodableRecord types that also adopt the standard Encodable protocol encode their date properties.

For example:

struct Player: EncodableRecord, Encodable {
    static let databaseDateEncodingStrategy: DatabaseDateEncodingStrategy = .timeIntervalSince1970

    var name: String
    var registrationDate: Date // encoded as an epoch timestamp
}

DatabaseUUIDEncodingStrategy specifies how EncodableRecord types that also adopt the standard Encodable protocol encode their UUID properties.

For example:

struct Player: EncodableProtocol, Encodable {
    static let databaseUUIDEncodingStrategy: DatabaseUUIDEncodingStrategy = .string

    // encoded in a string like "E621E1F8-C36C-495A-93FC-0C247A3E6E5F"
    var uuid: UUID
}

DatabaseDateDecodingStrategy specifies how FetchableRecord types that also adopt the standard Decodable protocol decode their date properties.

For example:

struct Player: FetchableRecord, Decodable {
    static let databaseDateDecodingStrategy: DatabaseDateDecodingStrategy = .timeIntervalSince1970

    var name: String
    var registrationDate: Date // decoded from epoch timestamp
}

A record change, given by a FetchedRecordsController to its change callback.

The move and update events hold a changes dictionary, whose keys are column names, and values the old values that have been changed.

An error thrown by a type that adopts PersistableRecord.

ValueScheduling controls how ValueObservation schedules the notifications of fresh values to your application.

A namespace for types related to the ValueReducer protocol.
