//! ```
//! use std::path::Path;
//! use gdal::Dataset;
//!
//! let dataset = Dataset::open(Path::new("fixtures/roads.geojson")).unwrap();
//! let mut layer = dataset.layer(0).unwrap();
//! for feature in layer.features() {
//!     let highway_field = feature.field("highway").unwrap().unwrap();
//!     let geometry = feature.geometry();
//!     println!("{} {}", highway_field.into_string().unwrap(), geometry.wkt().unwrap());
//! }
