Currently, GSW-Rust do not implement all functions already available in GSW-C or GSW-Matlab. This document gives an idea of what is missing. If interested in some specific function, please check our official manual as the best reference for what we have already done.

We organized the functions in modules following the toolbox card from TEOS-10 main document. The functions unchecked are missing in GSW-Rust. The goal is to implement all functions described in TEOS-10, but the priority is to do it right.
