Let’s install all we need.

Rust Tools

  1. Install the Rust toolchain following the steps in https://rustup.rs/

    • The Rust Toolchain is rustup plus many components cargo, rustc, the compiled std component and so on.

  2. Add the compiled std-component for our target microcontroller

  3. Add development components:

    rustup component add rust-analyzer rust-src

    rust-src is the std-component’s source code, used by rust-analyzer.
