Hello, i’m new to Elixir and Erlang world, but I want to create mechanism to restrict the use of a module through steps involving data. So I thought using finite state machine, with some states and data. But I need to execute some business logic to validate data and go to some state.

I also thought about map and struct with pattern matching but nothing prevent than a state was hard coded inside the struct.

For me the idea of state machine is really good and I though to replace struct by finite state machine with some logic inside.

Do you think is good concept or idea, or is it really bad?

Thanks
