Struct MultiPolygon 

#[repr(transparent)]
pub struct MultiPolygon<Pg: PolygonTrait>(pub Vec<Pg>);

Default MultiPolygon — a Vec<Pg> newtype where Pg is any concrete PolygonTrait implementor.

Mirrors boost::geometry::model::multi_polygon<Polygon> from boost/geometry/geometries/multi_polygon.hpp:48-92. The #[repr(transparent)] annotation guarantees the in-memory layout matches the underlying Vec<Pg>, mirroring the invariant Boost relies on by inheriting publicly from std::vector<Polygon> (boost/geometry/geometries/multi_polygon.hpp:55).

Implementations

impl<Pg: PolygonTrait> MultiPolygon<Pg>

pub const fn new() -> Self

Construct an empty multi-polygon.

Mirrors the default multi_polygon() constructor at boost/geometry/geometries/multi_polygon.hpp:63-65.

pub const fn from_vec(v: Vec<Pg>) -> Self

Wrap an existing Vec<Pg> as a multi-polygon without copying.

Rust analogue of the iterator-range multi_polygon(Iterator, Iterator) constructor at boost/geometry/geometries/multi_polygon.hpp:68-71.

pub fn push(&mut self, pg: Pg)

Append a polygon to the back of the multi-polygon.

Plays the role of std::vector::push_back on the inherited base_type in boost/geometry/geometries/multi_polygon.hpp:55-59.

Trait Implementations

impl<Pg: Clone + PolygonTrait> Clone for MultiPolygon<Pg>

fn clone(&self) -> MultiPolygon<Pg>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Pg: Debug + PolygonTrait> Debug for MultiPolygon<Pg>

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

Formats the value using the given formatter.

impl<Pg: PolygonTrait> Default for MultiPolygon<Pg>

fn default() -> Self

Returns the “default value” for a type.

impl<Pg: PolygonTrait> Geometry for MultiPolygon<Pg>

Tag this concrete type as a MultiPolygon. Mirrors the traits::tag<model::multi_polygon<...>> specialisation at boost/geometry/geometries/multi_polygon.hpp:100-115.

type Kind = MultiPolygonTag

One of the *Tag types from geometry_tag.

type Point = <Pg as Geometry>::Point

The point type this geometry is built from. For a value modelling Point, this is Self.

impl<Pg: PolygonTrait> MultiPolygon for MultiPolygon<Pg>

Wire the MultiPolygon concept up. The polygons() iterator hands back self.0.iter() — slice::Iter is already ExactSizeIterator. Plays the role of boost::begin(mpg) / boost::end(mpg) on model::multi_polygon (boost/geometry/geometries/multi_polygon.hpp:55-59).

type ItemPolygon = Pg

The element polygon type.

fn polygons(&self) -> impl ExactSizeIterator<Item = &Pg>

The polygons of this multi-polygon, in declared order.

impl<Pg: PartialEq + PolygonTrait> PartialEq for MultiPolygon<Pg>

fn eq(&self, other: &MultiPolygon<Pg>) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<A, const D: usize, OldCs, T, Cs, const CW: bool, const CL: bool> RebindGeometry<T, Cs> for MultiPolygon<Polygon<Point<A, D, OldCs>, CW, CL>>

where A: CoordinateScalar, OldCs: CoordinateSystem, T: CoordinateScalar, Cs: CoordinateSystem,

type Output = MultiPolygon<Polygon<Point<T, D, Cs>, CW, CL>>

The corresponding rebound stock model.
