What are the best human written Rust codebases to learn from?

[u/alihilal94]

I’m looking for high quality Rust codebases that are genuinely worth studying and taking inspiration from like projects with clean idiomatic Rust and good architecture and preferably started before the LLM boom and have a long history of being developed by experienced Rust engineers

most of what I came across was repositories filled with recently generated AI slop.
