The networking implementations I've had to do were all made a lot easier moving to async/await from hand-written state machines. It's a reduction in LOC terms of 6x or so, and the logic is much, much easier to follow. State machines are viable if your transition function is such that effectively every combination of (state, input) leads to a different state. If the transition function is mostly describing "go to the (single) next state or error," then you're essentially asking the user to do a lot of bookkeeping that compilers are good at and users are bad at. |
