Methods

impl GeoJson

pub fn from_json_object(object: Map<String, JsonValue>) -> Result<Self, Error>

pub fn from_json_value(value: JsonValue) -> Result<Self, Error>

Converts a JSON Value into a GeoJson object.

Example

use std::convert::TryInto;
use geojson::{Feature, GeoJson, Geometry, Value};
use serde_json::json;

let json_value = json!({
    "type": "Feature",
    "geometry": {
        "type": "Point",
        "coordinates": [102.0, 0.5]
    },
    "properties": null,
});

assert!(json_value.is_object());

let geojson: GeoJson = json_value.try_into().unwrap();

assert_eq!(
    geojson,
    GeoJson::Feature(Feature {
        bbox: None,
        geometry: Some(Geometry::new(Value::Point(vec![102.0, 0.5]))),
        id: None,
        properties: None,
        foreign_members: None,
    })
);
