cgns-rust

A way to read/write CGNS files from rust code.

cgns-sys

Bindgen around the CGNS MLL (repo, docs).

Issues with using the MLL (instead of CGIO):

• It is not thread-safe
• It performs transformation at file opening time (to expose the latest API on older files)
• Due to the API, when it transforms data and you then read that data, you are storing it in memory twice
• There is an issue with CGNS 3.4 files: CGNS/CGNS#355 (comment)

cgns-rust

Rust wrapper around cgns-sys.
