Quick google search points out this blog post for tips and tricks for prototyping stuff like game features in Rust: https://corrode.dev/blog/prototyping/
Definitely something that I’m going to try when I have to time to get back into Rust. Probably good advice for most people who are unhappy with Rust. Being attracted by Rust’s unique optimization tools too early on seems like a big beginner trap.

For what it’s worth, Ive been using Ansible off and on at work for 8 years, and I think it’s pretty outdated and clunky these days, there are much smarter ways to manage workloads such as kubernetes, cloud-init, terraform, and NixOS. If you don’t want to get into Kubernetes then definitely learn NixOS.
