Struct conway::universe::Region

pub struct Region { /* fields omitted */ }

Rectangular area within a Universe.

Methods

impl Region

A region is a rectangular area within a Universe. All coordinates are game coordinates.

pub fn new(left: isize, top: isize, width: usize, height: usize) -> Self

Creates a new region given x and y coordinates of top-left corner, and width and height, all in units of cells (game coordinates). Width and height must both be positive.

pub fn left(&self) -> isize

Returns the x coordinate of the leftmost cells of the Region, in game coordinates.

pub fn right(&self) -> isize

Returns the x coordinate of the rightmost cells of the Region, in game coordinates.

pub fn top(&self) -> isize

Returns the y coordinate of the uppermost cells of the Region, in game coordinates.

pub fn bottom(&self) -> isize

Returns the y coordinate of the lowermost cells of the Region, in game coordinates.

pub fn width(&self) -> usize

Returns the width of the Region (along x axis), in game coordinates.

pub fn height(&self) -> usize

Returns the height of the Region (along y axis), in game coordinates.

pub fn contains(&self, col: isize, row: isize) -> bool

Determines whether the specified cell is part of the Region.

pub fn intersection(&self, other: Region) -> Option<Region>

Trait Implementations
