What do you mean by this? Rust has multiple game engines that support hot reloading and/ or scripting.

This the bare minimum, https://liveplusplus.tech/

Also supports is kind of relative,

"CHR is very new and experimental feature of the engine, it is based on wildly unsafe functionality which could result in memory corruption, subtle bugs, etc."

Why is that the bare minimum?

I also think that doc page is a little old. The feature is over 2 years old now and hot reloading is inherently "unsafe" in any compiled language. It's just letting you know that Rust's safety guarantees might go out the window if there are bugs in the code that handles hot-reloading.

That live reload probably already works with Rust — they say they don't parse any source code, and instead analyze the compiled binary and debug info.
