difflicious.generic.auto

Derives a Differ for T, recursively deriving any missing field Differ instances.

Unlike derived, this does not require every field's Differ to already be in implicit scope. If a field instance is available, that instance is used. Otherwise, Difflicious attempts to derive the missing field instance and then lets ordinary implicit search build the field Differ. This means existing instances such as collection, option, either, tuple, or user-defined instances still take precedence over structural derivation of those types.

Use this when you want semi-automatic derivation at a specific call site without enabling difflicious.generic.auto for the surrounding scope.
