Struct geo_types::Rect

pub struct Rect<T> where
    T: CoordinateType,  { /* fields omitted */ }

An axis-aligned bounded 2D rectangle whose area is defined by minimum and maximum Coordinates.

The constructors and setters ensure the maximum Coordinate is greater than or equal to the minimum. Thus, a Rects width, height, and area is guaranteed to be greater than or equal to zero.

Note. While Rect implements MapCoords and RotatePoint algorithmic traits, the usage is expected to maintain the axis alignment. In particular, only rotation by integer multiples of 90 degrees, will preserve the original shape. In other cases, the min, and max points are rotated or transformed, and a new rectangle is created (with coordinate swaps to ensure min < max).

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 0., y: 4.},
    Coordinate { x: 3., y: 10.},
);

assert_eq!(3., rect.width());
assert_eq!(6., rect.height());
assert_eq!(
    Coordinate { x: 1.5, y: 7. },
    rect.center()
);

Implementations

impl<T: CoordinateType> Rect<T>

pub fn new<C>(min: C, max: C) -> Rect<T> where
    C: Into<Coordinate<T>>, 

Constructor to creates a new rectangle from coordinates, where min denotes to the coordinates of the bottom-left corner, and max denotes to the coordinates of the top-right corner

Panics

Panics if min's x/y coordinate is larger than that of the max's.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 0., y: 0. },
    Coordinate { x: 10., y: 20. }
);

pub fn try_new<C>(
    min: C,
    max: C
) -> Result<Rect<T>, InvalidRectCoordinatesError> where
    C: Into<Coordinate<T>>, 

pub fn min(self) -> Coordinate<T>

Returns the minimum Coordinate (bottom-left corner) of the Rect.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 5., y: 5. },
    Coordinate { x: 15., y: 15. },
);

assert_eq!(rect.min(), Coordinate { x: 5., y: 5. });

pub fn set_min<C>(&mut self, min: C) where
    C: Into<Coordinate<T>>, 

Set the Rect’s minimum coordinate.

Panics

Panics if min’s x/y is greater than the maximum coordinate’s x/y.

pub fn max(self) -> Coordinate<T>

Returns the maximum Coordinate (top-right corner) of the Rect.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 5., y: 5. },
    Coordinate { x: 15., y: 15. },
);

assert_eq!(rect.max(), Coordinate { x: 15., y: 15. });

pub fn set_max<C>(&mut self, max: C) where
    C: Into<Coordinate<T>>, 

Set the Rect’s maximum coordinate.

Panics

Panics if max’s x/y is less than the minimum coordinate’s x/y.

pub fn width(self) -> T

Returns the width of the Rect.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 5., y: 5. },
    Coordinate { x: 15., y: 15. },
);

assert_eq!(rect.width(), 10.);

pub fn height(self) -> T

Returns the height of the Rect.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 5., y: 5. },
    Coordinate { x: 15., y: 15. },
);

assert_eq!(rect.height(), 10.);

pub fn to_polygon(self) -> Polygon<T>

Create a Polygon from the Rect.

Examples

use geo_types::{Coordinate, Rect, polygon};

let rect = Rect::new(
    Coordinate { x: 0., y: 0. },
    Coordinate { x: 10., y: 20. },
);

assert_eq!(
    rect.to_polygon(),
    polygon![
        (x: 0., y: 0.),
        (x: 0., y: 20.),
        (x: 10., y: 20.),
        (x: 10., y: 0.),
        (x: 0., y: 0.),
    ],
);

impl<T: CoordinateType + Float> Rect<T>

pub fn center(self) -> Coordinate<T>

Returns the center Coordinate of the Rect.

Examples

use geo_types::{Coordinate, Rect};

let rect = Rect::new(
    Coordinate { x: 5., y: 5. },
    Coordinate { x: 15., y: 15. },
);

assert_eq!(
    rect.center(),
    Coordinate { x: 10., y: 10. }
);
