NAME CHANGE:

This crate was originally published under the name geoarrow2 because someone else had reserved the crate name geoarrow. That person did not plan to work on geoarrow and transferred ownership of that name to me, so future releases will be under the geoarrow crate name.

geoarrow-rs

A Rust implementation of the GeoArrow specification and bindings to GeoRust algorithms for efficient spatial operations on GeoArrow memory.

This repository also includes JavaScript (WebAssembly) bindings, wrapping the GeoArrow memory layout and offering vectorized geometry operations.

Documentation

• JavaScript library: https://kylebarron.dev/geoarrow-rs/js
• Rust wasm-bindgen library: https://docs.rs/geoarrow-wasm/latest/geoarrow_wasm/

Examples

Install

Add this to your Cargo.toml:

geoarrow = { package = "geoarrow2", version = "0.1" }

This will let you reference the package name as geoarrow in your code, even though the name on Crates.io is geoarrow2. Sadly the name geoarrow is squatted on by an empty package.
