Rust is actually interesting as a binding because no need for memory management AND no garbage collector needed either.
But yeah, if you want to use it you have to write extern C api yourself and do BP → C++ → C → Rust…
Then Rust → C → C++ → BP.
That is very annoying code to deal with once you go above the HelloWorld level.
Btw I know that some AAA studio migrated to Rust doing that, just don’t remember which one. Maybe was “Ready at Dawn”, not sure.
