# Struct bevy::math::URect

``````#[repr(C)]pub struct URect {
pub min: UVec2,
pub max: UVec2,
}``````
Expand description

A rectangle defined by two opposite corners.

The rectangle is axis aligned, and defined by its minimum and maximum coordinates, stored in `URect::min` and `URect::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: UVec2`

The minimum corner point of the rect.

§`max: UVec2`

The maximum corner point of the rect.

## Implementations§

§

### impl URect

#### pub const EMPTY: URect = _

An empty `URect`, represented by maximum and minimum corner points with `max == UVec2::MIN` and `min == UVec2::MAX`, so the rect has an extremely large negative size. This is useful, because when taking a union B of a non-empty `URect` A and this empty `URect`, B will simply equal A.

#### pub fn new(x0: u32, y0: u32, x1: u32, y1: u32) -> URect

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 = URect::new(0, 4, 10, 6); // w=10 h=2
let r = URect::new(2, 4, 5, 0); // w=3 h=4``````

#### pub fn from_corners(p0: UVec2, p1: UVec2) -> URect

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 = URect::from_corners(UVec2::ZERO, UVec2::ONE); // w=1 h=1
// Same; the points do not need to be ordered
let r = URect::from_corners(UVec2::ONE, UVec2::ZERO); // w=1 h=1``````

#### pub fn from_center_size(origin: UVec2, size: UVec2) -> URect

Create a new rectangle from its center and size.

##### §Rounding Behaviour

If the size contains odd numbers they will be rounded down to the nearest whole number.

##### §Panics

This method panics if any of the components of the size is negative or if `origin - (size / 2)` results in any negatives.

##### §Examples
``````let r = URect::from_center_size(UVec2::ONE, UVec2::splat(2)); // w=2 h=2
assert_eq!(r.min, UVec2::splat(0));
assert_eq!(r.max, UVec2::splat(2));``````

#### pub fn from_center_half_size(origin: UVec2, half_size: UVec2) -> URect

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 or if `origin - half_size` results in any negatives.

##### §Examples
``````let r = URect::from_center_half_size(UVec2::ONE, UVec2::ONE); // w=2 h=2
assert_eq!(r.min, UVec2::splat(0));
assert_eq!(r.max, UVec2::splat(2));``````

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

Check if the rectangle is empty.

##### §Examples
``````let r = URect::from_corners(UVec2::ZERO, UVec2::new(0, 1)); // w=0 h=1
assert!(r.is_empty());``````

#### pub const fn width(&self) -> u32

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

##### §Examples
``````let r = URect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.width(), 5);``````

#### pub const fn height(&self) -> u32

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

##### §Examples
``````let r = URect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.height(), 1);``````

#### pub fn size(&self) -> UVec2

Rectangle size.

##### §Examples
``````let r = URect::new(0, 0, 5, 1); // w=5 h=1
assert_eq!(r.size(), UVec2::new(5, 1));``````

#### pub fn half_size(&self) -> UVec2

Rectangle half-size.

##### §Rounding Behaviour

If the full size contains odd numbers they will be rounded down to the nearest whole number when calculating the half size.

##### §Examples
``````let r = URect::new(0, 0, 4, 2); // w=4 h=2
assert_eq!(r.half_size(), UVec2::new(2, 1));``````

#### pub fn center(&self) -> UVec2

The center point of the rectangle.

##### §Rounding Behaviour

If the (min + max) contains odd numbers they will be rounded down to the nearest whole number when calculating the center.

##### §Examples
``````let r = URect::new(0, 0, 4, 2); // w=4 h=2
assert_eq!(r.center(), UVec2::new(2, 1));``````

#### pub fn contains(&self, point: UVec2) -> bool

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

##### §Examples
``````let r = URect::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: URect) -> URect

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 = URect::new(0, 0, 5, 1); // w=5 h=1
let r2 = URect::new(1, 0, 3, 8); // w=2 h=4
let r = r1.union(r2);
assert_eq!(r.min, UVec2::new(0, 0));
assert_eq!(r.max, UVec2::new(5, 8));``````

#### pub fn union_point(&self, other: UVec2) -> URect

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 = URect::new(0, 0, 5, 1); // w=5 h=1
let u = r.union_point(UVec2::new(3, 6));
assert_eq!(u.min, UVec2::ZERO);
assert_eq!(u.max, UVec2::new(5, 6));``````

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

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 (`URect::is_empty()` returns `true`), but the actual values of `URect::min` and `URect::max` are implementation-dependent.

##### §Examples
``````let r1 = URect::new(0, 0, 2, 2); // w=2 h=2
let r2 = URect::new(1, 1, 3, 3); // w=2 h=2
let r = r1.intersect(r2);
assert_eq!(r.min, UVec2::new(1, 1));
assert_eq!(r.max, UVec2::new(2, 2));``````

#### pub fn inflate(&self, expansion: i32) -> URect

Create a new rectangle by expanding it evenly on all sides.

A positive expansion value produces a larger rectangle, while a negative expansion value produces a smaller rectangle. If this would result in zero width or height, `URect::EMPTY` is returned instead.

##### §Examples
``````let r = URect::new(4, 4, 6, 6); // w=2 h=2
let r2 = r.inflate(1); // w=4 h=4
assert_eq!(r2.min, UVec2::splat(3));
assert_eq!(r2.max, UVec2::splat(7));

let r = URect::new(4, 4, 8, 8); // w=4 h=4
let r2 = r.inflate(-1); // w=2 h=2
assert_eq!(r2.min, UVec2::splat(5));
assert_eq!(r2.max, UVec2::splat(7));``````

#### pub fn as_rect(&self) -> Rect

Returns self as `Rect` (f32)

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

Returns self as `IRect` (i32)
