a Rust library for creating hierarchical state machines
I've come to prefer modeling state machines with nested states, but implementing them by hand requires a large amount of error-prone boilerplate that obscures the important logic of the state machine. I found that the existing offerings in the Rust ecosystem - while inspiring - lacked a number of features that I was looking for, so I spent the last few months building moku. Feedback is welcome!
In plain words
Moku is a Rust library for building hierarchical state machines with nested states. It reduces boilerplate code that typically obscures state machine logic when implemented manually. The library provides features designed to address gaps in existing Rust state machine tools, making it easier for developers to create complex state machine implementations without error-prone repetitive code.

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
