Struct geo_types::geometry::Rect

source ·
pub struct Rect<T: CoordNum = f64> { /* private fields */ }
Expand description

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

The constructors and setters ensure the maximum Coord 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::{coord, Rect};

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

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

Implementations§

Creates a new rectangle from two corner coordinates.

Examples
use geo_types::{coord, Rect};

let rect = Rect::new(
    coord! { x: 10., y: 20. },
    coord! { x: 30., y: 10. }
);
assert_eq!(rect.min(), coord! { x: 10., y: 10. });
assert_eq!(rect.max(), coord! { x: 30., y: 20. });
👎Deprecated since 0.6.2: Use Rect::new instead, since Rect::try_new will never Error

Returns the minimum Coord of the Rect.

Examples
use geo_types::{coord, Rect};

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

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

Set the Rect’s minimum coordinate.

Panics

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

Returns the maximum Coord of the Rect.

Examples
use geo_types::{coord, Rect};

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

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

Set the Rect’s maximum coordinate.

Panics

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

Returns the width of the Rect.

Examples
use geo_types::{coord, Rect};

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

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

Returns the height of the Rect.

Examples
use geo_types::{coord, Rect};

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

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

Create a Polygon from the Rect.

Examples
use geo_types::{coord, Rect, polygon};

let rect = Rect::new(
    coord! { x: 0., y: 0. },
    coord! { x: 1., y: 2. },
);

assert_eq!(
    rect.to_polygon(),
    polygon![
        (x: 0., y: 0.),
        (x: 0., y: 2.),
        (x: 1., y: 2.),
        (x: 1., y: 0.),
        (x: 0., y: 0.),
    ],
);

Split a rectangle into two rectangles along the X-axis with equal widths.

Examples
let rect = geo_types::Rect::new(
    geo_types::coord! { x: 0., y: 0. },
    geo_types::coord! { x: 4., y: 4. },
);

let [rect1, rect2] = rect.split_x();

assert_eq!(
    geo_types::Rect::new(
        geo_types::coord! { x: 0., y: 0. },
        geo_types::coord! { x: 2., y: 4. },
    ),
    rect1,
);
assert_eq!(
    geo_types::Rect::new(
        geo_types::coord! { x: 2., y: 0. },
        geo_types::coord! { x: 4., y: 4. },
    ),
    rect2,
);

Split a rectangle into two rectangles along the Y-axis with equal heights.

Examples
let rect = geo_types::Rect::new(
    geo_types::coord! { x: 0., y: 0. },
    geo_types::coord! { x: 4., y: 4. },
);

let [rect1, rect2] = rect.split_y();

assert_eq!(
    geo_types::Rect::new(
        geo_types::coord! { x: 0., y: 0. },
        geo_types::coord! { x: 4., y: 2. },
    ),
    rect1,
);
assert_eq!(
    geo_types::Rect::new(
        geo_types::coord! { x: 0., y: 2. },
        geo_types::coord! { x: 4., y: 4. },
    ),
    rect2,
);

Returns the center Coord of the Rect.

Examples
use geo_types::{coord, Rect};

let rect = Rect::new(
    coord! { x: 5., y: 5. },
    coord! { x: 15., y: 15. },
