The lonlat_bng crate provides functions that convert decimal (WGS84 / ETRS89) longitude
and latitude coordinates into British National Grid coordinates, and vice versa.
This library makes use of the OSTN02 transformations
These functions transform input longitude and latitude coordinates to OSGB36 Eastings and Northings with high accuracy, and are suitable for use in surveying and construction. Please run your own tests, though.
Note that lon, lat coordinates outside the UK bounding box will be transformed to (NAN, NAN), which cannot be mapped.

lonlat_bng::convert_to_osgb36_threaded_vec(vec![&-0.32824866], vec![&51.44533267]);
lonlat_bng::convert_osgb36_to_lonlat_threaded_vec(vec![&516276], vec![&173141]);
The crate also provides C-compatible wrapper functions which are intended for use with FFI.
An example FFI implementation using Python can be found at Convertbng.
