Expand description

Geometries can have 0, 1, or two dimensions. Or, in the case of an empty geometry, a special Empty dimensionality.

Examples

use geo_types::{Point, Rect, line_string};
use geo::dimensions::{HasDimensions, Dimensions};

let point = Point::new(0.0, 5.0);
let line_string = line_string![(x: 0.0, y: 0.0), (x: 5.0, y: 5.0), (x: 0.0, y: 5.0)];
let rect = Rect::new((0.0, 0.0), (10.0, 10.0));
assert_eq!(Dimensions::ZeroDimensional, point.dimensions());
assert_eq!(Dimensions::OneDimensional, line_string.dimensions());
assert_eq!(Dimensions::TwoDimensional, rect.dimensions());

assert!(point.dimensions() < line_string.dimensions());
assert!(rect.dimensions() > line_string.dimensions());

Variants

Empty

Some geometries, like a MultiPoint or GeometryCollection may have no elements - thus no dimensions. Note that this is distinct from being ZeroDimensional, like a Point.

ZeroDimensional

Dimension of a point

OneDimensional

Dimension of a line or curve

TwoDimensional

Dimension of a surface
