Struct GeoFeature 

pub struct GeoFeature {
    pub id: Option<GeoValue>,
    pub geometry: Geometry,
    pub properties: GeoProperties,
}

A single geographic feature consisting of an optional id, a Geometry, and GeoProperties.

This mirrors a GeoJSON Feature: geometry holds the spatial data, properties stores arbitrary typed attributes, and id is optional. GeoFeature provides constructors and utilities for setting properties and converting geometries, plus serialization to a GeoJSON-compatible representation.

Fields

id: Option<GeoValue>

Optional feature identifier. If present, it is emitted as the GeoJSON id field.

geometry: Geometry

The feature’s spatial component.

properties: GeoProperties

Key–value attributes associated with the feature (emitted as GeoJSON properties).

Implementations

impl GeoFeature

pub fn new(geometry: Geometry) -> Self

Creates a new GeoFeature with the given geometry, no id, and empty properties.

Examples

let geom = Geometry::new_example();
let feature = GeoFeature::new(geom);

pub fn set_id(&mut self, id: GeoValue)

Sets the optional identifier of the feature (serialized as GeoJSON id).

pub fn set_properties(&mut self, properties: GeoProperties)

Replaces the entire properties map with the provided GeoProperties.

pub fn set_property<T>(&mut self, key: String, value: T)

where GeoValue: From<T>,

Inserts or updates a single property value.

Accepts any type T that can be converted into GeoValue (e.g., strings, numbers, booleans). The key is stored verbatim and will appear in the GeoJSON properties object.

pub fn to_single_geometry(&mut self)

Converts the inner geometry to its single variant if it is currently a multi-geometry.

If the geometry is already single, this is a no-op.

pub fn to_multi_geometry(&mut self)

Converts the inner geometry to its multi variant if it is currently a single-geometry.

If the geometry is already multi, this is a no-op.

pub fn to_json(&self, precision: Option<u8>) -> JsonObject

Serializes the feature into a GeoJSON-compatible JsonObject.

The output object contains type: "Feature", an optional id, a geometry member, and the properties object. If precision is provided, coordinate values in the geometry are rounded to that many fractional digits.

Trait Implementations

impl Clone for GeoFeature

fn clone(&self) -> GeoFeature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeoFeature

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

Formats the value using the given formatter.

impl From<MultiPolygon> for GeoFeature

Creates a GeoFeature from a geo::MultiPolygon<f64> by wrapping it as a Geometry and initializing id to None and properties to empty.

fn from(geometry: MultiPolygon<f64>) -> Self

Converts to this type from the input type.
