Struct geo::geometry::Polygon

pub struct Polygon<T = f64>
where
    T: CoordNum,
{ /* private fields */ }

A bounded two-dimensional area.

A Polygon’s outer boundary (exterior ring) is represented by a LineString. It may contain zero or more holes (interior rings), also represented by LineStrings.

A Polygon can be created with the Polygon::new constructor or the polygon! macro.

Semantics

The boundary of the polygon is the union of the boundaries of the exterior and interiors. The interior is all the points inside the polygon (not on the boundary).

The Polygon structure guarantees that all exterior and interior rings will be closed, such that the first and last Coord of each ring has the same value.

Validity

• The exterior and interior rings must be valid LinearRings (see LineString).

• No two rings in the boundary may cross, and may intersect at a Point only as a tangent. In other words, the rings must be distinct, and for every pair of common points in two of the rings, there must be a neighborhood (a topological open set) around one that does not contain the other point.

• The closure of the interior of the Polygon must equal the Polygon itself. For instance, the exterior may not contain a spike.

• The interior of the polygon must be a connected point-set. That is, any two distinct points in the interior must admit a curve between these two that lies in the interior.

Refer to section 6.1.11.1 of the OGC-SFA for a formal definition of validity. Besides the closed LineString guarantee, the Polygon structure does not enforce validity at this time. For example, it is possible to construct a Polygon that has:

• fewer than 3 coordinates per LineString ring
• interior rings that intersect other interior rings
• interior rings that extend beyond the exterior ring

LineString closing operation

Some APIs on Polygon result in a closing operation on a LineString. The operation is as follows:

If a LineString’s first and last Coord have different values, a new Coord will be appended to the LineString with a value equal to the first Coord.

Implementations

impl<T> Polygon<T>

where T: CoordNum,

pub fn new(exterior: LineString<T>, interiors: Vec<LineString<T>>) -> Polygon<T>

Create a new Polygon with the provided exterior LineString ring and interior LineString rings.

Upon calling new, the exterior and interior LineString rings will be closed.

Examples

Creating a Polygon with no interior rings:

use geo_types::{LineString, Polygon};

let polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![],
);

Creating a Polygon with an interior ring:

use geo_types::{LineString, Polygon};

let polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![LineString::from(vec![
        (0.1, 0.1),
        (0.9, 0.9),
        (0.9, 0.1),
        (0.1, 0.1),
    ])],
);

If the first and last Coords of the exterior or interior LineStrings no longer match, those LineStrings will be closed:

use geo_types::{coord, LineString, Polygon};

let mut polygon = Polygon::new(LineString::from(vec![(0., 0.), (1., 1.), (1., 0.)]), vec![]);

assert_eq!(
    polygon.exterior(),
    &LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.),])
);

pub fn into_inner(self) -> (LineString<T>, Vec<LineString<T>>)

Consume the Polygon, returning the exterior LineString ring and a vector of the interior LineString rings.

Examples

use geo_types::{LineString, Polygon};

let mut polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![LineString::from(vec![
        (0.1, 0.1),
        (0.9, 0.9),
        (0.9, 0.1),
        (0.1, 0.1),
    ])],
);

let (exterior, interiors) = polygon.into_inner();

assert_eq!(
    exterior,
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.),])
);

assert_eq!(
    interiors,
    vec![LineString::from(vec![
        (0.1, 0.1),
        (0.9, 0.9),
        (0.9, 0.1),
        (0.1, 0.1),
    ])]
);

pub fn exterior(&self) -> &LineString<T>

Return a reference to the exterior LineString ring.

Examples

use geo_types::{LineString, Polygon};

let exterior = LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]);

let polygon = Polygon::new(exterior.clone(), vec![]);

assert_eq!(polygon.exterior(), &exterior);

pub fn exterior_mut<F>(&mut self, f: F)

where F: FnOnce(&mut LineString<T>),

Execute the provided closure f, which is provided with a mutable reference to the exterior LineString ring.

After the closure executes, the exterior LineString will be closed.

Examples

use geo_types::{coord, LineString, Polygon};

let mut polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![],
);

polygon.exterior_mut(|exterior| {
    exterior.0[1] = coord! { x: 1., y: 2. };
});

assert_eq!(
    polygon.exterior(),
    &LineString::from(vec![(0., 0.), (1., 2.), (1., 0.), (0., 0.),])
);

If the first and last Coords of the exterior LineString no longer match, the LineString will be closed:

use geo_types::{coord, LineString, Polygon};

let mut polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![],
);

polygon.exterior_mut(|exterior| {
    exterior.0[0] = coord! { x: 0., y: 1. };
});

assert_eq!(
    polygon.exterior(),
    &LineString::from(vec![(0., 1.), (1., 1.), (1., 0.), (0., 0.), (0., 1.),])
);

pub fn try_exterior_mut<F, E>(&mut self, f: F) -> Result<(), E>

where F: FnOnce(&mut LineString<T>) -> Result<(), E>,

Fallible alternative to exterior_mut.

pub fn interiors(&self) -> &[LineString<T>]

    (0.9, 0.1),
    (0.1, 0.1),
])];

let polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    interiors.clone(),
);

assert_eq!(interiors, polygon.interiors());

pub fn interiors_mut<F>(&mut self, f: F)

where F: FnOnce(&mut [LineString<T>]),

Execute the provided closure f, which is provided with a mutable reference to the interior LineString rings.

After the closure executes, each of the interior LineStrings will be closed.

Examples

use geo_types::{coord, LineString, Polygon};

let mut polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),

        (0.1, 0.1),
        (0.9, 0.9),
        (0.9, 0.1),
        (0.1, 0.1),
    ])],
);

polygon.interiors_mut(|interiors| {
    interiors[0].0[1] = coord! { x: 0.8, y: 0.8 };
});

assert_eq!(
    polygon.interiors(),
    &[LineString::from(vec![
        (0.1, 0.1),
        (0.8, 0.8),
        (0.9, 0.1),
        (0.1, 0.1),
    ])]
);

If the first and last Coords of any interior LineString no longer match, those LineStrings will be closed:

use geo_types::{coord, LineString, Polygon};

let mut polygon = Polygon::new(
    LineString::from(vec![(0., 0.), (1., 1.), (1., 0.), (0., 0.)]),
    vec![LineString::from(vec![
        (0.1, 0.1),
        (0.9, 0.9),
        (0.9, 0.1),
        (0.1, 0.1),
    ])],
);

polygon.interiors_mut(|interiors| {
    interiors[0].0[0] = coord! { x: 0.1, y: 0.2 };
});

assert_eq!(
    polygon.interiors(),
    &[LineString::from(vec![
        (0.1, 0.2),

Some geometries, like a MultiPoint, can have zero coordinates - we call these empty.

fn dimensions(&self) -> Dimensions

The dimensions of some geometries are fixed, e.g. a Point always has 0 dimensions. However for others, the dimensionality depends on the specific geometry instance - for example typical Rects are 2-dimensional, but it’s possible to create degenerate Rects which have either 1 or 0 dimensions.

fn boundary_dimensions(&self) -> Dimensions

The dimensions of the Geometry’s boundary, as used by OGC-SFA.
