This allows you to manage Rust versions globally through `rustup`. - Alternatively, you can install `rustup` through `configuration.nix` and nixpkgs for a system-wide Rust setup.

2. **Troubleshooting Compilation Issues:** 2. **Troubleshooting Compilation Issues:**
If you encounter issues during Rust compilation, particularly those related to OpenSSL, SQLite, Wayland, or any other program utilized by `pkg-config` in the compilation process (see [here](https://nixos.wiki/wiki/Rust#Building_Rust_crates_that_require_external_system_libraries)), you can employ the `nix-shell -p pkg-config {your_dependency} [other_dependencies] --run fish` command. This command opens a Nix shell with the necessary dependencies, facilitating seamless code compilation. If you encounter issues during Rust compilation, particularly those related to OpenSSL, SQLite, Wayland, or any other program utilized by `pkg-config` in the compilation process (see [here](https://nixos.wiki/wiki/Rust#Building_Rust_crates_that_require_external_system_libraries)), you can employ the `nix-shell -p pkg-config {your_dependency} [other_dependencies] --run fish` command. This command opens a Nix shell with the necessary dependencies, facilitating seamless code compilation. Alternatively, you can employ the approach outlined in the initial section (Installation Customization) by utilizing `flake.nix` with dev shell instead of `nix-shell`.
Moreover, when using the Nix shell, be aware that the compilation takes place in the runtime directory, which might be insufficient for certain projects. To address this, you can adjust the runtime directory size in the `configuration.nix` file under `services.logind.extraConfig="RuntimeDirectorySize=8G"`. Moreover, when using the Nix Dev shell, be aware that the compilation takes place in the runtime directory, which might be insufficient for certain projects. To address this, you can adjust the runtime directory size in the `configuration.nix` file under `services.logind.extraConfig="RuntimeDirectorySize=8G"`.

For cross-compilation, consider using tools like `zigbuild` or `cross`. Personally, I find `zigbuild` preferable, but both are valuable options for your cross-compilation needs.
