Enum geo_types::geometry::Geometry

pub enum Geometry<T: CoordNum = f64> {
    Point(Point<T>),
    Line(Line<T>),
    LineString(LineString<T>),
    Polygon(Polygon<T>),
    MultiPoint(MultiPoint<T>),
    MultiLineString(MultiLineString<T>),
    MultiPolygon(MultiPolygon<T>),
    GeometryCollection(GeometryCollection<T>),
    Rect(Rect<T>),
    Triangle(Triangle<T>),
}

An enum representing any possible geometry type.

All geometry variants (Point, LineString, etc.) can be converted to a Geometry using Into::into. Conversely, TryFrom::try_from can be used to convert a Geometry back to one of it’s specific enum members.

Example

use std::convert::TryFrom;
use geo_types::{Point, point, Geometry, GeometryCollection};
let p = point!(x: 1.0, y: 1.0);
let pe: Geometry = p.into();
let pn = Point::try_from(pe).unwrap();

Variants

Point(Point<T>)

Line(Line<T>)

LineString(LineString<T>)

Polygon(Polygon<T>)

MultiPoint(MultiPoint<T>)

MultiLineString(MultiLineString<T>)

MultiPolygon(MultiPolygon<T>)

GeometryCollection(GeometryCollection<T>)

Rect(Rect<T>)

Triangle(Triangle<T>)
