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.

Install

Add this to your Cargo.toml:

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.
