@ibagail It's relatively simple to setup Rust on Windows with https://rustup.rs/
What may surprise you is that the rustup by default installs the MSVC version which requires you to install Visual Studio toolchain. If you install the GNU version you will be able to run it from command line without Visual Studio.
After installing with rustup, you can run `cargo new --bin directoryname` to make a new project directory pre-populated with boilerplates for a hello world binary. Your main source code file is `src/main.rs`.
If you want to add more source files, create a new file under `src` like `src/util.rs`, and add `mod util;` in `src/main.rs` to use its contents. If you see an error for structs and fns not found, make sure you have prepended `pub` to them in `src/util.rs`.
