Rust

The easiest way to manage Rust with Devbox is to install rustup, and then configure the channel you wish to install via Devbox's init_hook. You can also use the init_hook to configure rustup to install the Rust toolchain locally.

Example Repo

{
    "packages": [
        "rustup@latest",
        "libiconv@latest"
    ],
    "shell": {
        "init_hook": [
            "projectDir=$(dirname $(readlink -f \"$0\"))",
            "rustupHomeDir=\"$projectDir\"/.rustup",
            "mkdir -p $rustupHomeDir",
            "export RUSTUP_HOME=$rustupHomeDir",
            "export LIBRARY_PATH=$LIBRARY_PATH:\"$projectDir/nix/profile/default/lib\"",
            "rustup default stable",
            "cargo fetch"
        ],
        "scripts": {
            "test": "cargo test -- --show-output",
            "start" : "cargo run",
            "build-docs": "cargo doc"
        }
    }
}

To pin a specific version of Rust with Rustup, you can add a rust-toolchain.toml and check it into source control.
