Implementations

impl Geometry

pub fn point(x: f64, y: f64) -> Self

Constructs a 2D point geometry.

pub fn point_z(x: f64, y: f64, z: f64) -> Self

Constructs a 3D point geometry.

pub fn line_string(coords: Vec<Coord>) -> Self

Constructs a line string geometry.

pub fn polygon(exterior: Vec<Coord>, interiors: Vec<Vec<Coord>>) -> Self

Constructs a polygon geometry from exterior and interior coordinate rings.

pub fn multi_point(pts: Vec<Coord>) -> Self

Constructs a multipoint geometry.

pub fn multi_line_string(lines: Vec<Vec<Coord>>) -> Self

Constructs a multilinestring geometry.

pub fn multi_polygon(polys: Vec<(Vec<Coord>, Vec<Vec<Coord>>)>) -> Self

Constructs a multipolygon geometry.

pub fn geom_type(&self) -> GeometryType

Returns the geometry type discriminator.

pub fn has_z(&self) -> bool

Returns true if any coordinate in the geometry has a Z value.

pub fn is_empty(&self) -> bool

Returns true if geometry has no coordinates/components.

pub fn all_coords(&self) -> Vec<&Coord>

Returns flattened coordinate references across all nested components.

pub fn bbox(&self) -> Option<BBox>

Computes an axis-aligned bounding box for the geometry.

pub fn to_wkt(&self) -> String

Serializes geometry to WKT text (diagnostic output).

pub fn to_wkb(&self) -> Vec<u8>

Encode to ISO WKB (little-endian).

pub fn from_wkb(data: &[u8]) -> Result<Self>

Decode from ISO WKB.

pub fn to_gpkg_wkb(&self, srs_id: i32) -> Vec<u8>

Encode to GeoPackage WKB (GP header + ISO WKB + optional XY envelope).

pub fn from_gpkg_wkb(data: &[u8]) -> Result<(Self, i32)>

Decode from GeoPackage WKB. Returns (geometry, srs_id).

Trait Implementations

impl Clone for Geometry

fn clone(&self) -> Geometry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Geometry

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

Formats the value using the given formatter.

impl PartialEq for Geometry

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