A pluggable sealed API result type for modeling Retrofit responses. By default, Retrofit uses exceptions to propagate any errors. This library leverages Kotlin sealed types to better model these responses with a type-safe single point of return and no exception handling needed. ApiResult has two sealed subtypes: Success and Failure. Success is typed to T with no error type and Failure is typed to E with no success type. Failure in turn is represented by four sealed subtypes of its own: Failure.NetworkFailure, Failure.ApiFailure, Failure.HttpFailure, and Failure.UnknownFailure. This allows for simple handling of results through a consistent, non-exceptional flow via sealed when branches.
