In what way? Rust (cargo technically) might have the best support for offline compilation of any language I use. `cargo vendor` does pretty much everything I want it to.
Also you can download documentation for offline using `cargo doc` so you can easily lookup stuff during a flight. Although you do need to figure out all your dependencies ahead of time so that you download their documentation before you leave.
Just FYI, `cargo doc` doesn't download the documentation. It re-generates the documentation from source. You only need the source code to generate documentation.
