# Force RustRover to semi-work with Rust installs from Nixpkgs
2
+
3
+
- Tested with a toolchain from Nixpkgs, see examples/nixpkgs.nix and Fenix, see examples/fenix.nix
4
+
- Works by creating a toolchain in your `.idea` folder
5
+
6
+
TODO:
7
+
8
+
- [ ] A proper API for adding native libraries for linking
9
+
- [ ] An example of using in Flakes (without relying on `toString ./.` being the impure project root)
