Struct geo_types::geometry::Rect

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

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()
);
