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(())
}

Rust-Geohash for Substrate

This is a fork which derives SCALE codec info for use with parity substrate

Rust-Geohash is a Rust library for Geohash algorithm. Ported from node-geohash module.
