SetupResult

public enum SetupResult<T> : Hashable where T : StorageInterface

The SetupResult indicates the result of an asynchronous initialization of a persistent store. The SetupResult can be treated as a boolean:

try! CoreStore.addStorage(
    SQLiteStore(),
    completion: { (result: SetupResult) -> Void in
        if result {
            // succeeded
        }
        else {
            // failed
        }
    }
)

or as an enum, where the resulting associated object can also be inspected:

try! CoreStore.addStorage(
    SQLiteStore(),
    completion: { (result: SetupResult) -> Void in
        switch result {
        case .success(let storage):
            // storage is the related StorageInterface instance
        case .failure(let error):
            // error is the CoreStoreError enum value for the failure
        }
    }
)
  • SetupResult.success indicates that the storage setup succeeded. The associated object for this enum value is the related StorageInterface instance.

    Declaration

    Swift

    case success(T)
  • SetupResult.failure indicates that the storage setup failed. The associated object for this value is the related CoreStoreError enum value.

    Declaration

    Swift

    case failure(CoreStoreError)
  • Returns true if the result indicates .success, false if the result is .failure.

    Declaration

    Swift

    public var isSuccess: Bool { get }
  • Declaration

    Swift

    public func hash(into hasher: inout Hasher)
  • Declaration

    Swift

    public var debugDescription: String { get }
