Struct Rect 

pub struct Rect {
    pub x: f64,
    pub y: f64,
    pub width: f64,
    pub height: f64,
}

An axis-aligned rectangle.

Fields

x: f64

y: f64

width: f64

height: f64

Implementations

impl Rect

pub const ZERO: Rect

pub const fn new(x: f64, y: f64, width: f64, height: f64) -> Self

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

pub fn between(a: Point, b: Point) -> Self

The rectangle two corners describe, in any order — a marquee, a selection bounds, a drag rectangle.

pub fn origin(&self) -> Point

pub fn size(&self) -> Size

pub fn center(&self) -> Point

pub fn max_x(&self) -> f64

pub fn max_y(&self) -> f64

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

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

pub fn intersects(&self, other: Rect) -> bool

Whether the rectangles touch or overlap (touching counts).

pub fn expanded(&self, by: f64) -> Rect

The same rectangle with by of room added on every side.

pub fn distance_to_edge(&self, point: Point) -> f64

How far a point is from this rectangle’s outline: negative inside, positive outside, zero exactly on it.

A band around the outline is then one comparison rather than four, and it can straddle the line — which is what a border a person can grab has to do, because the line they are aiming at has no thickness.

pub fn bounds(rects: impl IntoIterator<Item = Self>) -> Option<Self>

The rectangle covering all of rects, or None when there are none.
