This abstraction contains either a success data of generic type `T` or an error of type `ErrorCode` as its result.
enum ErrorCode: Equatable, Error {
case unknown
// Top level server error
case serverIssue
// Network
case noNetworkConnection
}
enum DataResult<T> {
case success(value: T)
case error(ErrorCode)
var value: T? {
switch self {
case .success(value: let value):
return value
case .error:
return nil
}
}
var error: ErrorCode? {
switch self {
case .success:
return nil
case let .error(error):
return error
}
}
}
extension DataResult: Equatable where T: Equatable {}
