Rust Reverse Geocoder
A fast reverse geocoder in Rust. Inspired by Python reverse-geocoder.

Description
rrgeo takes a latitude and longitude as input and returns the closest city, country, latitude, and longitude, using a k-d tree to efficiently find the nearest neighbour based on a known list of locations. This can be useful if you need to reverse geocode a large number of coordinates quickly, or just need the rough location of coordinates but don't want the expense or complication of an online reverse geocoder.
This project contains (via Cargo workspaces) a library, an Axum REST API, an Actix REST API, a Warp REST API, and a command-line utility.
