This article is about the [rust programming language](https://www.rust-lang.org).

Rust Nightlies

Either use [rust overlay](https://nixos.org/nixpkgs/manual/#using-the-rust-nightlies-overlay) or rustup to get install rust nightlies.

Neovim Completion

Racer completion can be configured using the following snippet:

(neovim.override {
  configure = {
    customRC = ''
      if filereadable($HOME . "/.vimrc")
        source ~/.vimrc
      endif
      let $RUST_SRC_PATH = '${stdenv.mkDerivation {
        inherit (rustc) src;
        inherit (rustc.src) name;
        phases = ["unpackPhase" "installPhase"];
        installPhase = ''cp -r library $out'';
      }}'
    '';
    packages.nixbundle.start = with vimPlugins; [
      nvim-completion-manager
      nvim-cm-racer
    ];
  };
})

-== Emacs integration ==
-Making Emacs use certain version of libraries can be tricky, in particular for example OpenSSL might not be found ''even'' if it is in your Nix store. Two solutions exists :
-* a "global" one
-* a per-project one
-Both solution relies on the usage of a library called [https://github.com/direnv/direnv/wiki/Nix direnv] and its package integration in Emacs [https://github.com/wbolster/emacs-direnv emacs-direnv].
-=== Global solution ===
-If you happen to have all of your Rust projects in one folder "<code>/path/to/your/rust</code>" then placing a file <code>/path/to/your/rust/.envrc</code> with this content :
-<syntaxHighlight lang="shell">
-use_nix
-</syntaxHighlight>
-and  another file <code>/path/to/your/rust/default.nix</code> :
-<syntaxHighlight lang="Nix">
-let
-  moz_overlay = import (builtins.fetchTarball https://github.com/mozilla/nixpkgs-mozilla/archive/master.tar.gz);
-  nixpkgs = import <nixpkgs> { overlays = [ moz_overlay ]; };
-  ruststable = (nixpkgs.latest.rustChannels.stable.rust.override { extensions = [ "rust-src" "rls-preview" "rust-analysis" "rustfmt-preview" ];});
-in
-  with nixpkgs;
-  stdenv.mkDerivation {
-    name = "rust";
-    buildInputs = [ openssl pkg-config nasm rustup ruststable cmake zlib ];
-  }
-</syntaxHighlight>
-will, for example, grant you a free acces to OpenSSL ! Feel free to override this to your liking !
-=== Per-project solution ===
-For a more granular solution to this problem a more in-depth review of [https://github.com/direnv/direnv/wiki/Nix#persistent-shell-for-speeding-things-up the direnv wiki] will be poorly be needed !
