}

A decoded GeoPackage geometry value.

Coordinates are always (x, y) pairs — typically (longitude, latitude) for geographic SRSs or (easting, northing) for projected ones.

Variants

Point

A single point.

Fields

x: f64

X coordinate (longitude / easting).

y: f64

Y coordinate (latitude / northing).

LineString

An ordered sequence of points forming a line.

Fields

coords: Vec<(f64, f64)>

Coordinate pairs along the line.

Polygon

A polygon defined by one exterior ring and zero or more interior rings.

Fields

rings: Vec<Vec<(f64, f64)>>

Rings: index 0 is the exterior ring; subsequent entries are holes.

MultiPoint

A collection of points.

Fields

points: Vec<(f64, f64)>

Individual point coordinates.

MultiLineString

A collection of line strings.

Fields

lines: Vec<Vec<(f64, f64)>>

Individual line strings, each as a coordinate sequence.

MultiPolygon

A collection of polygons.

Fields

polygons: Vec<Vec<Vec<(f64, f64)>>>

Individual polygons, each as a list of rings.

GeometryCollection(Vec<GpkgGeometry>)

A heterogeneous collection of geometries.

Empty

An explicitly empty geometry (GeoPackage envelope-indicator = 0, empty flag set).

Implementations

impl GpkgGeometry

pub fn geometry_type(&self) -> &'static str

Return the OGC geometry-type name (uppercase).

pub fn point_count(&self) -> usize

Return the total number of coordinate points in this geometry.

pub fn bbox(&self) -> Option<(f64, f64, f64, f64)>

Return the axis-aligned bounding box (min_x, min_y, max_x, max_y), or None for empty / zero-point geometries.

Trait Implementations

impl Clone for GpkgGeometry

fn clone(&self) -> GpkgGeometry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpkgGeometry

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

Formats the value using the given formatter.

impl PartialEq for GpkgGeometry

fn eq(&self, other: &GpkgGeometry) -> 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.
