Struct Rect 

pub struct Rect {
    pub x: i32,
    pub y: i32,
    pub w: i32,
    pub h: i32,
}

A rectangle of cells. A non-positive w or h means empty.

Fields

x: i32

Left column.

y: i32

Top row.

w: i32

Width in cells.

h: i32

Height in cells.

Implementations

impl Rect

pub const fn new(x: i32, y: i32, w: i32, h: i32) -> Rect

Builds a rectangle.

pub const fn is_empty(&self) -> bool

Whether the rectangle has no cells.

pub fn contains(&self, x: i32, y: i32) -> bool

Whether cell (x, y) lies inside.

pub fn intersect(&self, other: &Rect) -> Option<Rect>

The overlap of two rectangles, or None if they don’t overlap.
