Cross-compiling Rust in Windows

After making a lot of confusion with Rust cross-compiling, I finally managed to compile WinSafe x32 programs in my Windows x64. The root of the misunderstanding is that, in order to cross compile, you must have the following installed:

• MSVC build tools;
• Rust toolchain;
• Rust target.

Toolchain relevant commands:

rustup toolchain list
rustup toolchain install stable-i686-pc-windows-msvc
rustup toolchain uninstall stable-i686-pc-windows-msvc

Target relevant commands:

rustup target list | grep installed
rustup target add i686-pc-windows-msvc --toolchain stable
rustup target remove i686-pc-windows-msvc

To verify if you program has any linker issues, build and run:

rustup run stable-i686-pc-windows-msvc cargo run
rustup run stable-x86_64-pc-windows-msvc cargo run

Then finally the program can be built for release with:

RUSTFLAGS='-C target-feature=+crt-static' cargo build --release --target i686-pc-windows-msvc
RUSTFLAGS='-C target-feature=+crt-static' cargo build --release --target x86_64-pc-windows-msvc

I only found all that stuff after posting a question on StackOverflow and receiving this comment. The documentation was completely absent in providing any useful information.
