Struct iron_shapes::rect::Rect

pub struct Rect<T> {
    pub lower_left: Point<T>,
    pub upper_right: Point<T>,
}

Fields

lower_left: Point<T>

Implementations

impl<T: PartialOrd + Copy> Rect<T>

pub fn new<C>(c1: C, c2: C) -> Selfwhere C: Into<Point<T>>,

Construct the bounding box of the two points. Order does not matter.

Examples

use iron_shapes::prelude::*;

// Create a rectangle based on two corner points.
let rect1 = Rect::new(Point::new(0, 0), Point::new(1, 2));
// Any type that implements `Into<Point<T>>` can be used for the corner points.
let rect2 = Rect::new((1, 2), (0, 0));
// Ordering of the corner points does not matter.
assert_eq!(rect1, rect2);
// Even though `(0, 0)` was passed as second argument it is recognized as lower left corner.
assert_eq!(rect2.lower_left(), Point::new(0, 0));

impl<T: Copy> Rect<T>

pub fn lower_left(&self) -> Point<T>

pub fn upper_left(&self) -> Point<T>

pub fn upper_right(&self) -> Point<T>

pub fn lower_right(&self) -> Point<T>

Get the lower right corner.

impl<T: PartialOrd + Copy> Rect<T>

pub fn contains_point(&self, p: Point<T>) -> bool

Check if rectangle contains the point. Inclusive boundaries.

Example

use iron_shapes::prelude::*;
let rect = Rect::new((0, 0), (10, 20));
// Contains point somewhere in the center.
assert!(rect.contains_point(Point::new(5, 5)));
// Also contains point on the boundaries.
assert!(rect.contains_point(Point::new(0, 0)));
// Does not contain point outside of the rectangle.
assert!(!rect.contains_point(Point::new(10, 21)));

pub fn contains_point_exclusive(&self, p: Point<T>) -> bool

Check if rectangle contains the point. Exclusive boundaries.

Example

use iron_shapes::prelude::*;
let rect = Rect::new((0, 0), (10, 20));
// Contains point somewhere in the center.
assert!(rect.contains_point_exclusive(Point::new(5, 5)));
// Does not contain points on boundaries.
assert!(!rect.contains_point_exclusive(Point::new(0, 0)));
// Does not contain point outside of the rectangle.
assert!(!rect.contains_point_exclusive(Point::new(10, 21)));

pub fn contains_rectangle(&self, other: &Self) -> bool

Check if rectangle contains other rectangle. Inclusive boundaries.

Example

use iron_shapes::prelude::*;

let outer = Rect::new((0, 0), (2, 2));
let inner = Rect::new((0, 0), (1, 1));
assert!(outer.contains_rectangle(&inner));
assert!(!inner.contains_rectangle(&outer));

pub fn contains_rectangle_exclusive(&self, other: &Self) -> bool

Check if rectangle contains other rectangle. Exclusive boundaries.

Example

use iron_shapes::prelude::*;

let outer = Rect::new((0, 0), (3, 3));
let inner = Rect::new((1, 1), (2, 2));
assert!(outer.contains_rectangle_exclusive(&inner));
assert!(!inner.contains_rectangle_exclusive(&outer));

let not_inner = Rect::new((0, 0), (1, 1)); // This shares the boundary with `outer`.
assert!(!outer.contains_rectangle_exclusive(&not_inner));

pub fn touches(&self, other: &Self) -> bool

Test if the both rectangles touch each other, i.e. if they either share a boundary or are overlapping.

pub fn intersection(&self, other: &Self) -> Option<Self>

Compute the boolean intersection of two rectangles. This function excludes the boundaries, hence a zero-area intersection is considered None. See intersection_inclusive_bounds() zero-area intersections should be returned as Some(rectangle).

Example

use iron_shapes::prelude::*;

// Create two overlapping rectangles.
let a = Rect::new((0, 0), (2, 2));
let b = Rect::new((1, 1), (3, 3));

// Compute the intersection.
assert_eq!(a.intersection(&b), Some(Rect::new((1, 1), (2, 2))));

// Create a non-overlapping rectangle.
let c = Rect::new((100, 100), (200, 200));
// The intersection with a non-overlapping rectangle is `None`.
assert_eq!(a.intersection(&c), None);

pub fn intersection_inclusive_bounds(&self, other: &Self) -> Option<Self>

Compute the boolean intersection of two rectangles and include the boundaries. This allows to get zero-area intersection results for example if the two rectangles touch on a boundary or one of the rectangle is already zero-area.

Example

use iron_shapes::prelude::*;

// Create two rectangles which intersect in a single point.
let a = Rect::new((0, 0), (2, 2));
let b = Rect::new((2, 2), (3, 3));

// Compute the intersection.
assert_eq!(a.intersection_inclusive_bounds(&b), Some(Rect::new((2, 2), (2, 2))));

pub fn add_point(&self, point: Point<T>) -> Self

Create the smallest Rect that contains the original Rect and the point.

Example

use iron_shapes::prelude::*;

let r1 = Rect::new((0,0), (1,2));

let r2 = r1.add_point(Point::new(10, 11));

assert_eq!(r2, Rect::new((0,0), (10,11)));

pub fn add_rect(&self, rect: &Self) -> Self

Get the smallest Rect that contains both rectangles self and rect.

Example

use iron_shapes::prelude::*;

let r1 = Rect::new((0,0), (1,2));
let r2 = Rect::new((4,5), (6,7));

let r3 = r1.add_rect(&r2);

assert_eq!(r3, Rect::new((0,0), (6,7)));

impl<T: Sub<Output = T> + Copy + Ord + Zero> Rect<T>

pub fn distance_to_point(&self, p: Point<T>) -> Vector<T>

Compute the shortest from the rectangle to the point p. The distance is zero if the point is inside the rectangle.

Example

use iron_shapes::prelude::*;

let r = Rect::new((0,0), (10, 10));

assert_eq!(r.distance_to_point((5, 15).into()), Vector::new(0, 5));

// Distance to point inside the rectangle is zero.
assert_eq!(r.distance_to_point((5, 5).into()), Vector::new(0, 0));

impl<T: Copy + Add<Output = T> + Sub<Output = T> + PartialOrd> Rect<T>

pub fn sized(&self, add_x: T, add_y: T) -> Self

Create an enlarged copy of this rectangle. The vertical boundaries will be shifted towards the outside by add_x. The horizontal boundaries will be shifted towards the outside by add_y.
