Hello, I am very very new to rust. Quite a few site related to beginners level rust instructions mention to use rustup to install some rust packages. There is no rustup package in the guix package list. I have installed rust and rust-cargo. Specifically, I am trying to setup a build flow for stm32 microcontroller board based on the directions at https://docs.rust-embedded.org/book/intro/install.html I am stuck at having to do this step: sh> rustup target add thumbv7m-none-eabi
Any help about installing rustup in GUIX would be arppreciated -Milind
