Geohash
Geohash algorithm implementation in Rust. It encodes/decodes a longitude-latitude tuple into/from a hashed string. You can find more about geohash algorithm on Wikipedia
Usage
extern crate geohash;
use fixed::types::I64F64;
fn main() -> Result<(), Box<geohash::GeohashError>> {
use std::convert::TryFrom;
use geohash::{GeoHash, Direction};
let lon = I64F64::from_num(112.5584);
let lat = I64F64::from_num(37.8324f64);
// decode a geohash
let (lon, lat, _, _) = GeoHash::<9>::try_from("ww8p1r4t8")?.try_as_coordinates()?;
// find a neighboring hash
let sw = GeoHash::<9>::try_from("ww8p1r4t8")?.neighbor(Direction::SW)?;
Ok(())
}
