Enable generator diagnostics in the application configuration used while compiling the facade:
config :maxo_adapt, debug: trueMaxoAdapt then prints inspected generated AST and its formatted Elixir representation. Keep this disabled in routine development and CI because output can be large for behaviours with many callbacks.
At runtime, inspect the effective implementation directly:
MyApp.SessionRepo.__maxo_adapt__()
#=> MyApp.SessionRepo.PostgreSQLMutable configuration logs use the facade's :log option (:debug by default). Set log: false when configuration is expected and should remain silent, especially in tests and benchmarks.
When configuration validation fails, MaxoAdapt returns {:error, :invalid_adapter_implementation} and logs whether the module was missing or which required name/arity pairs were absent. The previous adapter remains active.
