Crate serde_geozero 

serde-geozero

A library for serializing and deserializing geospatial data using serde and geozero.

This crate provides functionality to convert between geospatial data sources and Rust types using serde’s serialization framework and geozero’s processing capabilities.

Disclaimer

This isn’t a fully fledged cargo crate as it’s still missing some functionality it claims to provide (serialization).

Features

• Deserialize from various geospatial formats (GeoJSON, FlatGeobuf, etc.) into Rust structs
• Collect geometry and property data from geospatial sources
• Serialize geometry data into different formats

Main Components

• [collector::GeozeroCollector] - Collects geometry and property data from geospatial sources
• from_datasource - Helper function to deserialize data from any GeozeroDatasource
• error::Error - Custom error types for the library

Example

use serde::{Deserialize, Serialize};
use geo::Geometry;
use serde_geozero::from_datasource;
use std::str::from_utf8;
use serde_geozero::ser::to_geozero_datasource;
use geozero::geojson::GeoJsonWriter;

#[derive(Deserialize, Serialize)]
struct City {
    geometry: Geometry,
    name: String,
    population: i64,
}

let geojson = r#"{
    "type": "Feature",
    "geometry": {
        "type": "Point",
        "coordinates": [13.4, 52.5]
    },
    "properties": {
        "name": "Berlin",
        "population": 3669495
    }
}"#;

let mut reader = geozero::geojson::GeoJsonReader(geojson.as_bytes());
let cities: Vec<City> = from_datasource(&mut reader).unwrap();


let mut out = Vec::new();

let mut writer = GeoJsonWriter::new(&mut out);

let result = to_geozero_datasource(cities.as_slice(), &mut writer);
assert!(result.is_ok(), "{}", result.unwrap_err());
assert_eq!(
    from_utf8(out.as_slice()).unwrap().to_string().retain(|c| !c.is_whitespace()),
    geojson.to_string().retain(|c| !c.is_whitespace())
    );
