I tried once building a very simple Rust extension on Windows using the Anaconda Python distribution and had no luck. If I remember correctly it got stuck trying to find the VC++ compiler.
Cython extensions on the other hand work fine with the MinGW GCC compiler provided by Anaconda, although it's pretty old (version 5).
