  /// Add a path to be watched with the specified recursive mode.

  /// # Arguments
  ///
  /// * `path` - The path to watch
  /// * `recursive_mode` - Whether to watch the path recursively or not

  ///
  /// A BuildResult indicating success or failure

  /// Some implementations may apply changes immediately in `add`/`remove`,
  /// in which case this is a no-op. Others may batch all operations
  /// and apply them only when `commit` is called.
