simple_network_handler_core

Core types shared by the simple_network_handler family: Failure, LocalizedFailure, TransportFailure, the sealed Result<T> (Ok/Err), and ExceptionMatcher.

You normally don't depend on this directly — simple_network_handler (Dio) and simple_network_handler_supabase re-export it. Depend on it directly only when a package of yours needs the failure/result vocabulary without any network layer.
