Derive Macros

DeserializeUntaggedVerboseError

The macro this crate revolves around. It is essentially a specialized version of the Deserialize macro from serde, which can only be applied to enums where every variant is a tuple struct with one field. It behaves in the same way as a combination of Deserialize and the untagged attribute, but returns a much more detailed (and verbose!) error in case of failure.
