/// The [`ReplayProcessor`] struct is a pivotal component in `subtr-actor`'s
/// replay parsing pipeline. It is designed to process and traverse an actor
/// graph of a Rocket League replay, and expose methods for collectors to gather
/// specific data points as it progresses through the replay.
///
/// The processor pushes frames from a replay through an [`ActorStateModeler`],
/// which models the state all actors in the replay at a given point in time.
/// The [`ReplayProcessor`] also maintains various mappings to allow efficient
/// lookup and traversal of the actor graph, thus assisting [`Collector`]
/// instances in their data accumulation tasks.
///
/// The primary method of this struct is [`process`](ReplayProcessor::process),
/// which takes a collector and processes the replay. As it traverses the
/// replay, it calls the [`Collector::process_frame`] method of the passed
/// collector, passing the current frame along with its contextual data. This
/// allows the collector to extract specific data from each frame as needed.
///
/// The [`ReplayProcessor`] also provides a number of helper methods for
/// navigating the actor graph and extracting information, such as
/// [`get_ball_rigid_body`](ReplayProcessor::get_ball_rigid_body),
/// [`get_player_name`](ReplayProcessor::get_player_name),
/// [`get_player_team_key`](ReplayProcessor::get_player_team_key),
/// [`get_player_is_team_0`](ReplayProcessor::get_player_is_team_0), and
/// [`get_player_rigid_body`](ReplayProcessor::get_player_rigid_body).

    /// - `player_to_actor_id`: maps a player's [`boxcars::UniqueId`] to their actor ID.
