    /// The keys to consider when caching builds for the project.

    /// Cache keys enable you to specify the files or directories that should trigger a rebuild when
    /// modified. By default, uv will rebuild a project whenever the `pyproject.toml`, `setup.py`,
    /// or `setup.cfg` files in the project directory are modified, or if a `src` directory is
    /// added or removed, i.e.:
    ///
    /// ```toml
    /// cache-keys = [{ file = "pyproject.toml" }, { file = "setup.py" }, { file = "setup.cfg" }, { dir = "src" }]
    /// ```
    ///
    /// As an example: if a project uses dynamic metadata to read its dependencies from a
    /// `requirements.txt` file, you can specify `cache-keys = [{ file = "requirements.txt" }, { file = "pyproject.toml" }]`
    /// to ensure that the project is rebuilt whenever the `requirements.txt` file is modified (in
    /// addition to watching the `pyproject.toml`).
    ///
    /// Globs are supported, following the syntax of the [`glob`](https://docs.rs/glob/0.3.1/glob/struct.Pattern.html)
    /// crate. For example, to invalidate the cache whenever a `.toml` file in the project directory
    /// or any of its subdirectories is modified, you can specify `cache-keys = [{ file = "**/*.toml" }]`.
    /// Note that the use of globs can be expensive, as uv may need to walk the filesystem to
    /// determine whether any files have changed.
    ///
    /// Cache keys can also include version control information. For example, if a project uses
    /// `setuptools_scm` to read its version from a Git commit, you can specify `cache-keys = [{ git = { commit = true }, { file = "pyproject.toml" }]`
    /// to include the current Git commit hash in the cache key (in addition to the
    /// `pyproject.toml`). Git tags are also supported via `cache-keys = [{ git = { commit = true, tags = true } }]`.
    ///
    /// Cache keys can also include environment variables. For example, if a project relies on
    /// `MACOSX_DEPLOYMENT_TARGET` or other environment variables to determine its behavior, you can
    /// specify `cache-keys = [{ env = "MACOSX_DEPLOYMENT_TARGET" }]` to invalidate the cache
    /// whenever the environment variable changes.
    ///
    /// Cache keys only affect the project defined by the `pyproject.toml` in which they're

    /// globs are interpreted as relative to the project directory.
