Struct Position

pub struct Position {
    pub row: usize,
    pub col: usize,
}

Position is a (row, col) position on a Grid.

For example such table has 4 cells. Which indexes are (0, 0), (0, 1), (1, 0), (1, 1).

Fields

row: usize

Row.

col: usize

Column.

Implementations

impl Position

pub const fn new(row: usize, col: usize) -> Position

Creates a new Position object.

pub const fn has_intersection(&self, point: Position) -> bool

A check whether a given cell has intersection with any other cell.

Example

let p = Position::new(3, 3);

assert!(p.has_intersection(p));
assert!(p.has_intersection(Position::new(1, 1)));
assert!(p.has_intersection(Position::new(3, 10)));
assert!(p.has_intersection(Position::new(10, 3)));

assert!(!p.has_intersection(Position::new(4, 4)));

pub const fn has_coverage(&self, point: Position) -> bool

A check whether a given cell has intersection with any other cell.

Example

let p = Position::new(3, 3);

assert!(p.has_coverage(Position::new(1, 1)));

assert!(!p.has_coverage(Position::new(3, 3)));
assert!(!p.has_coverage(Position::new(1, 10)));
assert!(!p.has_coverage(p));
