-=== VSCode integration ===
-The [https://marketplace.visualstudio.com/items?itemName=rust-lang.rust rust-lang.rust] and [https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer rust-lang.rust-analyzer] VSCode extensions offer Rust support. However, you'll need a few more ingredients to get everything working:
-<syntaxHighlight lang="nix">

-  # Pinned nixpkgs, deterministic. Last updated: 2/12/21.
-  pkgs = import (fetchTarball("https://github.com/NixOS/nixpkgs/archive/a58a0b5098f0c2a389ee70eb69422a052982d990.tar.gz")) {};
-  # Rolling updates, not deterministic.
-  # pkgs = import (fetchTarball("channel:nixpkgs-unstable")) {};
-in pkgs.mkShell {
-  buildInputs = [
-    pkgs.cargo
-    pkgs.rustc
-    pkgs.rustfmt
-  ];
-  # Certain Rust tools won't work without this
-  # This can also be fixed by using oxalica/rust-overlay and specifying the rust-src extension
-  # See https://discourse.nixos.org/t/rust-src-not-found-and-other-misadventures-of-developing-rust-on-nixos/11570/3?u=samuela. for more details.
-  RUST_SRC_PATH = "${pkgs.rust.packages.stable.rustPlatform.rustLibSrc}";
-}

-You can use the [https://marketplace.visualstudio.com/items?itemName=arrterian.nix-env-selector arrterian.nix-env-selector] extension to enable your nix-shell inside VSCode and have these settings picked up by other extensions.

 This will have the stable Rust compiler + the official formatter and linter inside the ephemeral shell. It'll also set the RUST_SRC_PATH environment variable to point to the right location, which tools, such as rust-analyzer, require to be set.
