DecodableResponseSerializer

public final class DecodableResponseSerializer<T> : ResponseSerializer where T : Decodable

A ResponseSerializer that decodes the response data as a generic value using any type that conforms to DataDecoder. By default, this is an instance of JSONDecoder. Additionally, a request returning nil or no data is considered an error. However, if the response is has a status code valid for empty responses (204, 205), then the Empty.value value is returned.

  • The JSONDecoder instance used to decode responses.
