Enum Geometry 

#[non_exhaustive]
pub enum Geometry {
    Point(Coord),
    LineString(LineString),
    Polygon(Polygon),
    MultiPoint(Vec<Coord>),
    MultiLineString(Vec<LineString>),
    MultiPolygon(Vec<Polygon>),
    GeometryCollection(Vec<Geometry>),
    Empty(GeometryType),
}

The geometry tree. Marked #[non_exhaustive] so future SemVer-minor releases can add variants (curves, surfaces, Z/M-bearing variants once the IR grows past 2D).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Point(Coord)

LineString(LineString)

Polygon(Polygon)

MultiPoint(Vec<Coord>)

MultiLineString(Vec<LineString>)

MultiPolygon(Vec<Polygon>)

GeometryCollection(Vec<Geometry>)

Empty(GeometryType)

A typed-empty geometry (e.g. POINT EMPTY, POLYGON EMPTY). The tag is preserved so WKB serialization round-trips correctly.

Implementations

impl Geometry

pub fn type_of(&self) -> GeometryType

pub fn is_empty(&self) -> bool

pub fn has_z(&self) -> bool

True if any coordinate in the tree carries a Z ordinate.

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

Compute the 2D bounding box [xmin, ymin, xmax, ymax].

Returns None for empty geometries (no coordinates to bound). NaN coordinates are skipped, so POINT EMPTY (stored as NaN/NaN) also yields None.

pub fn has_m(&self) -> bool

True if any coordinate in the tree carries an M ordinate.

impl Geometry

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

Encode as OGC Simple Features Well-Known Binary (little-endian, 2D).

pub fn write_wkb_into(&self, buf: &mut Vec<u8>)

Encode WKB into a caller-provided buffer (clears it first). Useful for row-by-row writers that want to reuse a scratch buffer.

impl Geometry

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

Decode OGC Simple Features WKB bytes into a Geometry.

Accepts both little-endian and big-endian, and respects per-nested byte-order bytes inside collections (the ISO WKB rule).

v0.1 returns Error::Unsupported for Z/M variants — the type code is recognized but ordinates beyond X/Y are not decoded.

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.
