//! [GDAL](http://gdal.org/) bindings for Rust.
//!
//! A high-level API to access the GDAL library, for vector and raster data.

//! ## Use

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