示例

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

// Print two features to the console in GeoJson format
fn main() -> anyhow::Result<()> {
    // If you want to write to a file, use BufWriter<File> instead
    let mut buf = vec![];

    // Any format that has an implementation of geozero::FeatureProcessor can be used,
    // such as wkt, shp, fgb, etc. See also https://docs.rs/geozero/latest/geozero/
    let mut geojson = GeoJsonWriter::new(&mut buf);

    // Serialize features to GeoJson format
    let mut ser = FeatureSerializer::new(&mut geojson);
    my_features().serialize(&mut ser)?;

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

// Create feature array
fn my_features() -> impl Serialize {
    [
        Station {
            name: "King's Cross",
            europe: true,
            loc: Point::new(51.5321, -0.1233),
        },
        Station {
            name: "Tokyo",
            europe: false,
            loc: Point::new(139.7661, 35.6812),
        },
    ]
}

// Geographic feature

    // Property
