Struct geo::GeometryCollection

pub struct GeometryCollection<T>(pub Vec<Geometry<T>>)
 where
    T: CoordinateType;

A collection of Geometry types.

Can be created from a Vec of Geometries, or from an Iterator which yields Geometries.

Iterating over this objects, yields the component Geometries.

Methods

impl<T> GeometryCollection<T> where
    T: CoordinateType, 

pub fn new() -> GeometryCollection<T>

Return an empty GeometryCollection

pub fn len(&self) -> usize

Number of geometries in this GeometryCollection

pub fn is_empty(&self) -> bool

Is this GeometryCollection empty
