[Too]

Last time i tried was a year ago so things might have changed but then i think lack of GUI libraries, and libraries in general, is the ugliest part of Rust ecosystem. Language-wise it's very friendly but once you want to interact with the outside world you many times end up having to wrap existing C or C++ libraries with FFI and that's not very fun. Especially not C++ libraries as C++ doesn't have a standard ABI and can't be called straight from rust so you first have to wrap the c++ library with 'extern C' and then call that C interface from rust FFI. Also making sure the C++ lib and rust is compiled in a binary compatible way on all platforms is quite a challenge.

Good IDE support, with autocomplete and integrated debugging, was also missing but that should have improved i believe?
