geoserde

| crates.io | docs.rs |

Serializer and deserializer for geospatial data.

The serializer currently only supports Point, Line, LineString or Polygon.

Deserializer is not yet implemented.

Getting started

Add the dependency.

cargo add geoserde

Examples

Serialize features (= geometry + properties) to json.

use geo_types::Point;
use geoserde::FeatureSerializer;
use geozero::geojson::GeoJsonWriter;
use serde::Serialize;

// feature
#[derive(Serialize)]
struct Station {
    loc: Point,         // geometry
    name: &'static str, // property
    europe: bool,       // property
}

fn main() -> anyhow::Result<()> {
    let features = vec![
        Station {
            loc: Point::new(51.5321, -0.1233),
            name: "King's Cross",
            europe: true,
        },
        Station {
            loc: Point::new(139.7661, 35.6812),
            name: "Tokyo",
            europe: false,
        },
    ];

    let mut buf = vec![];
    let mut json = GeoJsonWriter::new(&mut buf);
    let mut ser = FeatureSerializer::new(&mut json);
    features.serialize(&mut ser)?;

    println!("{}", std::str::from_utf8(&buf)?);
    Ok(())
}
