Struct MartState 

pub struct MartState<I: Copy + Eq + Hash + Debug> {
    pub inventory: MartStock<I>,
    pub phase: MartPhase,
}

Complete mart interaction state machine.

Construct with MartState::new, drive with MartState::update_frame once per input frame, passing the game’s MartBackend for all price/capacity/transaction decisions.

Fields

inventory: MartStock<I>

Items the shop stocks.

phase: MartPhase

Implementations

impl<I: Copy + Eq + Hash + Debug> MartState<I>

pub fn new(inventory: MartStock<I>) -> Self

Begin a mart session with the given shop stock.

pub fn update_frame<B: MartBackend<Item = I>>( &mut self, input: MenuInput, backend: &mut B, ) -> MartUpdate

Advance the mart state machine by one frame of input.

backend is consulted for bag contents and is mutated when a transaction is committed.
