typed finite-state machine
Advantages of type-fsm
-
Focus on the right message
-
Top-to-bottom design for easy refactoring
-
Conducive to building complex state machine systems
- Type guarantees will not produce incorrect function calls when written
- With the help of the type system, we can define many state processing functions and then call each other recursively with confidence.
- There is a sanity check. If you miss some items for pattern matching, the compiler will issue a warning, and there will also be a warning for invalid items.
