Struct State

pub struct State<'a> { /* private fields */ }

A struct representing the current game state. It contains the possible solutions for the verifier selection, the currently selected code (if any), the currently selected verifier (if any), whether a verifier was tested, as well as how many tests were performed.

Implementations

impl<'a> State<'a>

pub fn new(game: &'a Game) -> Self

pub fn possible_codes(self) -> Set

pub fn is_solved(self) -> bool

pub fn solution(self) -> Option<Code>

If solved, returns the solution. Otherwise, it returns None.

pub fn after_move( self, move_to_do: Move, ) -> Result<(State<'a>, Option<AfterMoveInfo>), AfterMoveError>

Return the state after performing the given move. If the given move is invalid, this function returns an error. In addition to the state itself, this function will sometimes provide additional information about the transition as the second argument of the tuple.

pub fn is_awaiting_result(&self) -> bool

Returns true if the game is awaiting a verifier answer.

pub fn possible_moves(&self) -> impl Iterator<Item = Move> + '_

Return all possible moves. Notably these are not verified in every way:

• Verifiers may return impossible results, leading to no solution.
• Codes or verifiers may be chosen that do not provide information to the player.

pub fn find_best_move(self) -> (GameScore, Move)

Find the best possible move to minimize the maximum amount of codes and verifier checks needed. The game must be at a state where the player chooses a code or a verifier.

Panics

This function will panic if the state is currently awaiting a verifier answer or if the game has already been solved.
