GeoHash-16
geohash-16 is a Rust crate for Geohash algorithm using a more simple and sane encoding method (classic Base16). Forked from geohash crate.
lib.rs
:
Geohash
Geohash algorithm implementation in Rust. It encodes/decodes a longitude-latitude tuple into/from a hashed string. You can find more about the original geohash algorithm on Wikipedia This crate provides an alternative base16 encoded version
Usage
extern crate geohash;
use std::error::Error;
use geohash::{encode, decode, neighbor, Direction, Coordinate};
fn main() -> Result<(), Box<Error>> {
// encode a coordinate
let c = Coordinate { x: 112.5584f64, y: 37.8324f64 };
println!("encoding 37.8324, 112.5584: {}", encode(c, 9usize)?);
// decode a geohash
let (c, _, _) = decode("e71150dc9")?;
println!("decoding ww8p1r4t8 to: {}, {}", c.y, c.x);
// find a neighboring hash
let sw = neighbor("e71150dc9", Direction::SW)?;
Ok(())
}
