Geometry Objects

GeoJSON Format Specification § 3.1

Examples

Constructing a Geometry:

use geojson::{Geometry, Value};

let geometry = Geometry::new(Value::Point(vec![7.428959, 1.513394]));

Geometries can be created from Values.

let geometry1: Geometry = Value::Point(vec![7.428959, 1.513394]).into();

Serializing a Geometry to a GeoJSON string:

use geojson::{GeoJson, Geometry, Value};
use serde_json;

let geometry = Geometry::new(Value::Point(vec![7.428959, 1.513394]));

let geojson_string = geometry.to_string();

assert_eq!(
    "{\"type\":\"Point\",\"coordinates\":[7.428959,1.513394]}",
    geojson_string,
);

Deserializing a GeoJSON string into a Geometry:

use geojson::{GeoJson, Geometry, Value};

let geojson_str = "{\"coordinates\":[7.428959,1.513394],\"type\":\"Point\"}";

let geometry = match geojson_str.parse::<GeoJson>() {
    Ok(GeoJson::Geometry(g)) => g,
    _ => return,
};

assert_eq!(
    Geometry::new(Value::Point(vec![7.428959, 1.513394]),),
    geometry,
);

Transforming a Geometry into a geo_types::Geometry<f64> (which requires the geo-types feature):

use geojson::{Geometry, Value};
use std::convert::TryInto;

let geometry = Geometry::new(Value::Point(vec![7.428959, 1.513394]));
let geom: geo_types::Geometry<f64> = geometry.try_into().unwrap();

Implementations

impl Geometry

pub fn new(value: Value) -> Geometry

Returns a new Geometry with the specified value. bbox and foreign_members will be set to None.

impl Geometry

pub fn from_json_object(object: Map<String, Value>) -> Result<Geometry, Error>

pub fn from_json_value(value: Value) -> Result<Geometry, Error>

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Geometry

fn deserialize<D>( deserializer: D, ) -> Result<Geometry, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Geometry

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

Formats the value using the given formatter.

impl<V> From<V> for Geometry

where V: Into<Value>,

fn from(v: V) -> Geometry

Converts to this type from the input type.

impl FromStr for Geometry

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Geometry, Error>

Parses a string s to return a value of this type.

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.

impl Serialize for Geometry

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<GeoJson> for Geometry

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: GeoJson) -> Result<Geometry, Error>

Performs the conversion.

impl TryFrom<Map<String, Value>> for Geometry

type Error = Error

The type returned in the event of a conversion error.

fn try_from(object: Map<String, Value>) -> Result<Geometry, Error>

Performs the conversion.

impl TryFrom<Value> for Geometry

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Geometry, Error>

Performs the conversion.
