Struct Rect 

pub struct Rect {
    pub origin: Point,
    pub size: Size,
}

An axis-aligned rectangle in logical pixels.

Fields

origin: Point

Top-left corner.

size: Size

Width and height.

Implementations

impl Rect

pub const ZERO: Self

An empty rectangle at the origin.

pub const fn new(x: f32, y: f32, width: f32, height: f32) -> Self

Creates a rectangle from its top-left corner and dimensions, in logical pixels.

pub const fn from_origin_size(origin: Point, size: Size) -> Self

Creates a rectangle from a top-left corner and a size.

pub fn x(&self) -> f32

Left edge.

pub fn y(&self) -> f32

Top edge.

pub fn width(&self) -> f32

Horizontal extent.

pub fn height(&self) -> f32

Vertical extent.

pub fn max_x(&self) -> f32

Right edge (x + width).

pub fn max_y(&self) -> f32

Bottom edge (y + height).

pub fn center(&self) -> Point

Center point.

pub fn contains(&self, p: Point) -> bool

Half-open containment: the left/top edges are inside, the right/bottom edges are not.

pub fn inflate(&self, amount: f32) -> Self

Grows the rectangle by amount on every side (shrinks for negative values).

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

The overlapping area, or an empty rectangle at the origin of self when the two do not overlap.

pub fn is_empty(&self) -> bool

Returns true when the width or height is zero or negative.

pub fn translate(&self, offset: Point) -> Self

Returns the rectangle moved by offset, keeping its size.
