• FFI & interop

Transforming coordinates from one coordinate reference system to another is slow, and usually done in bulk, so it’s a great candidate for low-level, multithreaded code, accessed via FFI from higher-level languages to facilitate easy I/O and visualisation. When Rust hit 1.0 last year, I decided to write a library to convert from latitude and longitude coordinates to British National Grid eastings and northings, in order to learn the language.
