Enumerations

A namespace for database Combine publishers.

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

A date modifier for SQLite date functions such as julianDay(_:_:) and dateTime(_:_:).

For more information, see https://www.sqlite.org/lang_datefunc.html

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.uppercaseString

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

DatabaseColumnEncodingStrategy specifies how EncodableRecord types that also adopt the standard Encodable protocol encode their coding keys into database columns.

For example:

struct Player: EncodableProtocol, Encodable {
    static let databaseColumnEncodingStrategy = DatabaseColumnEncodingStrategy.convertToSnakeCase

    // Encoded in the player_id column
    var playerID: String
}

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
}

DatabaseColumnDecodingStrategy specifies how FetchableRecord types that also adopt the standard Decodable protocol look for the database columns that match their coding keys.

For example:

struct Player: FetchableRecord, Decodable {
    static let databaseColumnDecodingStrategy = DatabaseColumnDecodingStrategy.convertFromSnakeCase

    // Decoded from the player_id column
    var playerID: Int
}

An error thrown by a type that adopts MutablePersistableRecord.

Controls the extent of the shared database observation of SharedValueObservation.

A namespace for types related to the ValueReducer protocol.
