Struct Pieces

pub struct Pieces { /* private fields */ }

A vector of pieces.

Invariants

We maintain that

• pieces will not overlap

Implementations

impl Pieces

pub fn standard_board() -> Self

Create a board with standard piece positions.

pub fn chess960_board(idx_ordering: impl FnOnce() -> [usize; 8]) -> Self

Create a board with a randomized back row.

This is known as the 960, or Fischer, variant setup.

pub fn get_piece(&self, x: f32, y: f32) -> Option<usize>

Get a piece’s index within inner, if it exists.

pub fn get(&self, index: usize) -> Option<&Piece>

pub fn get_mut(&mut self, index: usize) -> Option<&mut Piece>

pub fn inner_ref(&self) -> &[Piece]

pub fn inner_mut(&mut self) -> &mut Vec<Piece>

pub fn travel(&mut self, idx: usize, x: f32, y: f32) -> usize

Move the piece at idx to x, y.

Warnings

This may shuffle piece indices! Returns the piece’s new index.

pub fn travelable( &self, piece: &Piece, x: f32, y: f32, kind: TravelKind, ) -> bool

Trait Implementations

impl Clone for Pieces

fn clone(&self) -> Pieces

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
