# Struct bevy::prelude::Rect

``````#[repr(C)]pub struct Rect {
pub min: Vec2,
pub max: Vec2,
}``````
Expand description

A rectangle defined by two opposite corners.

The rectangle is axis aligned, and defined by its minimum and maximum coordinates, stored in `Rect::min` and `Rect::max`, respectively. The minimum/maximum invariant must be upheld by the user when directly assigning the fields, otherwise some methods produce invalid results. It is generally recommended to use one of the constructor methods instead, which will ensure this invariant is met, unless you already have the minimum and maximum corners.

## Fields§

§`min: Vec2`

The minimum corner point of the rect.

§`max: Vec2`

The maximum corner point of the rect.

## Implementations§

§

### impl Rect

#### pub fn new(x0: f32, y0: f32, x1: f32, y1: f32) -> Rect

Create a new rectangle from two corner points.

The two points do not need to be the minimum and/or maximum corners. They only need to be two opposite corners.

##### Examples
``````let r = Rect::new(0., 4., 10., 6.); // w=10 h=2
let r = Rect::new(2., 3., 5., -1.); // w=3 h=4``````

#### pub fn from_corners(p0: Vec2, p1: Vec2) -> Rect

Create a new rectangle from two corner points.

The two points do not need to be the minimum and/or maximum corners. They only need to be two opposite corners.

##### Examples
``````// Unit rect from [0,0] to [1,1]
let r = Rect::from_corners(Vec2::ZERO, Vec2::ONE); // w=1 h=1
// Same; the points do not need to be ordered
let r = Rect::from_corners(Vec2::ONE, Vec2::ZERO); // w=1 h=1``````

#### pub fn from_center_size(origin: Vec2, size: Vec2) -> Rect

Create a new rectangle from its center and size.

##### Panics

This method panics if any of the components of the size is negative.

##### Examples
``````let r = Rect::from_center_size(Vec2::ZERO, Vec2::ONE); // w=1 h=1
assert!(r.min.abs_diff_eq(Vec2::splat(-0.5), 1e-5));
assert!(r.max.abs_diff_eq(Vec2::splat(0.5), 1e-5));``````

#### pub fn from_center_half_size(origin: Vec2, half_size: Vec2) -> Rect

Create a new rectangle from its center and half-size.

##### Panics

This method panics if any of the components of the half-size is negative.

##### Examples
``````let r = Rect::from_center_half_size(Vec2::ZERO, Vec2::ONE); // w=2 h=2
assert!(r.min.abs_diff_eq(Vec2::splat(-1.), 1e-5));
assert!(r.max.abs_diff_eq(Vec2::splat(1.), 1e-5));``````

#### pub fn is_empty(&self) -> bool

Check if the rectangle is empty.

##### Examples
``````let r = Rect::from_corners(Vec2::ZERO, Vec2::new(0., 1.)); // w=0 h=1
assert!(r.is_empty());``````

#### pub fn width(&self) -> f32

Rectangle width (max.x - min.x).

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!((r.width() - 5.).abs() <= 1e-5);``````

#### pub fn height(&self) -> f32

Rectangle height (max.y - min.y).

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!((r.height() - 1.).abs() <= 1e-5);``````

#### pub fn size(&self) -> Vec2

Rectangle size.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!(r.size().abs_diff_eq(Vec2::new(5., 1.), 1e-5));``````

#### pub fn half_size(&self) -> Vec2

Rectangle half-size.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!(r.half_size().abs_diff_eq(Vec2::new(2.5, 0.5), 1e-5));``````

#### pub fn center(&self) -> Vec2

The center point of the rectangle.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!(r.center().abs_diff_eq(Vec2::new(2.5, 0.5), 1e-5));``````

#### pub fn contains(&self, point: Vec2) -> bool

Check if a point lies within this rectangle, inclusive of its edges.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
assert!(r.contains(r.center()));
assert!(r.contains(r.min));
assert!(r.contains(r.max));``````

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

Build a new rectangle formed of the union of this rectangle and another rectangle.

The union is the smallest rectangle enclosing both rectangles.

##### Examples
``````let r1 = Rect::new(0., 0., 5., 1.); // w=5 h=1
let r2 = Rect::new(1., -1., 3., 3.); // w=2 h=4
let r = r1.union(r2);
assert!(r.min.abs_diff_eq(Vec2::new(0., -1.), 1e-5));
assert!(r.max.abs_diff_eq(Vec2::new(5., 3.), 1e-5));``````

#### pub fn union_point(&self, other: Vec2) -> Rect

Build a new rectangle formed of the union of this rectangle and a point.

The union is the smallest rectangle enclosing both the rectangle and the point. If the point is already inside the rectangle, this method returns a copy of the rectangle.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
let u = r.union_point(Vec2::new(3., 6.));
assert!(u.min.abs_diff_eq(Vec2::ZERO, 1e-5));
assert!(u.max.abs_diff_eq(Vec2::new(5., 6.), 1e-5));``````

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

Build a new rectangle formed of the intersection of this rectangle and another rectangle.

The intersection is the largest rectangle enclosed in both rectangles. If the intersection is empty, this method returns an empty rectangle (`Rect::is_empty()` returns `true`), but the actual values of `Rect::min` and `Rect::max` are implementation-dependent.

##### Examples
``````let r1 = Rect::new(0., 0., 5., 1.); // w=5 h=1
let r2 = Rect::new(1., -1., 3., 3.); // w=2 h=4
let r = r1.intersect(r2);
assert!(r.min.abs_diff_eq(Vec2::new(1., 0.), 1e-5));
assert!(r.max.abs_diff_eq(Vec2::new(3., 1.), 1e-5));``````

#### pub fn inset(&self, inset: f32) -> Rect

Create a new rectangle with a constant inset.

The inset is the extra border on all sides. A positive inset produces a larger rectangle, while a negative inset is allowed and produces a smaller rectangle. If the inset is negative and its absolute value is larger than the rectangle half-size, the created rectangle is empty.

##### Examples
``````let r = Rect::new(0., 0., 5., 1.); // w=5 h=1
let r2 = r.inset(3.); // w=11 h=7
assert!(r2.min.abs_diff_eq(Vec2::splat(-3.), 1e-5));
assert!(r2.max.abs_diff_eq(Vec2::new(8., 4.), 1e-5));

let r = Rect::new(0., -1., 6., 7.); // w=6 h=8
let r2 = r.inset(-2.); // w=11 h=7
assert!(r2.min.abs_diff_eq(Vec2::new(2., 1.), 1e-5));
assert!(r2.max.abs_diff_eq(Vec2::new(4., 5.), 1e-5));``````

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

Build a new rectangle from this one with its coordinates expressed relative to `other` in a normalized ([0..1] x [0..1]) coordinate system.

##### Examples
``````let r = Rect::new(2., 3., 4., 6.);
let s = Rect::new(0., 0., 10., 10.);
let n = r.normalize(s);

assert_eq!(n.min.x, 0.2);
assert_eq!(n.min.y, 0.3);
assert_eq!(n.max.x, 0.4);
assert_eq!(n.max.y, 0.6);``````

#### pub fn as_irect(&self) -> IRect

Returns self as `IRect` (i32)

#### pub fn as_urect(&self) -> URect

Returns self as `URect` (u32)
