Struct MultiPolygonGeometry 

pub struct MultiPolygonGeometry(pub Vec<PolygonGeometry>);

Represents a collection of polygons, each of which may have an outer ring and optional inner holes. This struct is used for complex, multi-part areas in 2D space.

Trait Implementations

impl Clone for MultiPolygonGeometry

fn clone(&self) -> MultiPolygonGeometry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CompositeGeometryTrait<PolygonGeometry> for MultiPolygonGeometry

Implementation of CompositeGeometryTrait for MultiPolygonGeometry.

Provides methods for working with the internal list of PolygonGeometry objects.

• new() creates an empty MultiPolygonGeometry.
• as_vec() returns an immutable reference to the internal polygons.
• as_mut_vec() returns a mutable reference to the internal polygons.
• into_inner() consumes the geometry and returns the vector of polygons.

fn new() -> Self

Creates a new, empty composite geometry.

fn as_vec(&self) -> &Vec<PolygonGeometry>

Returns an immutable reference to the inner collection of elements.

fn as_mut_vec(&mut self) -> &mut Vec<PolygonGeometry>

Returns a mutable reference to the inner collection of elements.

fn into_inner(self) -> Vec<PolygonGeometry>

Consumes the composite geometry and returns the inner collection of elements.

fn into_iter(self) -> impl Iterator<Item = Item>

Returns an iterator over owned elements of the composite geometry.

fn into_first_and_rest(self) -> Option<(Item, Vec<Item>)>

Splits the composite geometry into its first element and the rest, if available.

fn is_empty(&self) -> bool

Checks whether the composite geometry contains no elements.

fn len(&self) -> usize

Returns the number of elements contained in the composite geometry.

fn push(&mut self, item: Item)

Adds a new element to the composite geometry.

fn pop(&mut self) -> Option<Item>

Removes and returns the last element from the composite geometry, if any.

fn first(&self) -> Option<&Item>

Returns a reference to the first element, if any.

fn last(&self) -> Option<&Item>

Returns a reference to the last element, if any.

fn first_mut(&mut self) -> Option<&mut Item>

Returns a mutable reference to the first element, if any.

fn last_mut(&mut self) -> Option<&mut Item>

Returns a mutable reference to the last element, if any.

impl Debug for MultiPolygonGeometry

Implementation of Debug for MultiPolygonGeometry.

Prints the list of polygons in a developer-friendly format.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> From<&'a [T]> for MultiPolygonGeometry

where PolygonGeometry: From<&'a T>,

fn from(value: &'a [T]) -> Self

Converts to this type from the input type.

impl<'a, T, const N: usize> From<&'a [T; N]> for MultiPolygonGeometry

where PolygonGeometry: From<&'a T>,

fn from(value: &'a [T; N]) -> Self

Converts to this type from the input type.

impl<'a, T> From<&'a Vec<T>> for MultiPolygonGeometry

where PolygonGeometry: From<&'a T>,

fn from(value: &'a Vec<T>) -> Self

Converts to this type from the input type.

impl<T> From<Vec<T>> for MultiPolygonGeometry

where PolygonGeometry: From<T>,

fn from(value: Vec<T>) -> Self

Converts to this type from the input type.

impl GeometryTrait for MultiPolygonGeometry

Implementation of GeometryTrait for MultiPolygonGeometry.

• area() returns the sum of all polygon areas.
• verify() checks that each polygon is valid.
• to_coord_json() converts the geometry into a JSON array of polygons, optionally rounding coordinates to a given precision.

fn area(&self) -> f64

Returns the geometric area of the geometry. For non-area geometries (e.g., points or lines), this returns 0.

fn verify(&self) -> Result<()>

Verifies the geometric validity of the geometry. For example, checks if there are enough points or if polygons are properly closed. Returns an error if the geometry is invalid.

fn to_coord_json(&self, precision: Option<u8>) -> JsonValue

Converts the geometry into a JSON representation of its coordinates. Optionally rounds coordinate values to the given precision.

fn contains_point(&self, x: f64, y: f64) -> bool

Checks if a point is inside this geometry.

fn to_mercator(&self) -> MultiPolygonGeometry

Transform this geometry from WGS84 to Web Mercator coordinates.

fn compute_bounds(&self) -> Option<[f64; 4]>

Compute the bounding box of this geometry.

impl PartialEq for MultiPolygonGeometry

fn eq(&self, other: &MultiPolygonGeometry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SingleGeometryTrait<MultiPolygonGeometry> for PolygonGeometry

fn into_multi(self) -> MultiPolygonGeometry

Wraps this polygon into a MultiPolygonGeometry.
