Enum PlayerAgent 

pub enum PlayerAgent<G: Game> {
    Human,
    Ai(Box<dyn Bot<G>>),
}

Who is deciding a seat’s moves.

A seat with no entry in Simulator’s agent map behaves like Human: it blocks Simulator::step rather than panicking or being skipped, so a game can add players without wiring every seat up front.

Variants

Human

A seat driven by external input via Simulator::select_human_action.

Ai(Box<dyn Bot<G>>)

A seat driven by a [Bot], asked for a move every time it is active.
