# Changes

## 0.24.1

* Modified conversion from JSON to reject zero- and one-dimensional positions.
  * PR: <https://github.com/georust/geojson/pull/225>

## 0.24.0

* Added `geojson::{ser, de}` helpers to convert your custom struct to and from GeoJSON. 
  * For external geometry types like geo-types, use the `serialize_geometry`/`deserialize_geometry` helpers.
  * Example:
    ```
    #[derive(Serialize, Deserialize)]
    struct MyStruct {
        #[serde(serialize_with = "serialize_geometry", deserialize_with = "deserialize_geometry")]
        geometry: geo_types::Point<f64>,
        name: String,
        age: u64,
    }

    // read your input
    let my_structs: Vec<MyStruct> = geojson::de::deserialize_feature_collection(geojson_reader).unwrap();

    // do some processing
    process(&mut my_structs);

    // write back your results
    geojson::ser::to_feature_collection_string(&my_structs).unwrap();
    ```
  * PR: <https://github.com/georust/geojson/pull/199>
* Added `geojson::{FeatureReader, FeatureWriter}` to stream the reading/writing of your custom struct to and from GeoJSON, greatly reducing the memory required to process a FeatureCollection.
