§gridish
A rust library for working with British and Irish national grids (OSGB, and OSI). Provides a simple interface for converting valid grid references into eastings / northings and vice versa, as well as functionality to recalculate a grid reference to a new precision. This crate intentionally does not provide functionality to convert between different coordinate systems, as there are already several libraries available to do this; it exists solely to fill the gap between numerical coordinates in eastings / northings and their textual representations.
§Examples
use gridish::{OSGB, Precision};
use geo_types::coord;
// Parse grid reference from a 6 figure (100m) string.
let gridref_100m: OSGB = "SO892437".parse().unwrap();
// Recalculate grid reference to 2 figures (10km)
let gridref_10k = gridref_100m.recalculate(Precision::_10Km);
assert_eq!("SO84".to_string(), gridref_10k.to_string());
// Get the eastings / northings at the gridref's south west corner
assert_eq!(gridref_100m.sw(), coord! {x: 389_200.0, y: 243_700.0 }.into());
assert_eq!(gridref_10k.sw(), coord! {x: 380_000.0, y: 240_000.0 }.into());§Features
serde: Provides support for (de)serialization using serde.tetrads: Provides support for tetrad grid references in the DINTY format, as commonly used in biological surveys.

- OSGB
- Type representing a valid British National Grid Reference. Can be instantiated either by parsing from a string or through a valid set of eastings and northings as coordinates.
- OSI
- Type representing a valid Irish National Grid Reference. Can be instantiated either by parsing from a string or through a valid set of eastings and northings as coordinates.
