The Oxidation wiki page has a section containing some documentation about writing Rust code in Firefox. It's a real mish-mash, containing links to: in-tree docs, a dev-platform email thread, a wiki page, an MDN page, a slide deck, and a blog post.

This pieces of documentation should be consolidated, probably as in-tree docs because that seems to be the preferred approach nowadays. I'm not sure exactly what structure would be best... one the one hand, it would be nice to have all the info about writing Rust code in a single section. On the other hand, we already have separate sections for code, the build system, testing, etc., so perhaps I should split things up according to those sections, and then the Oxidation wiki could just have links to the relevant sections.

Bug 1428139 is still open but that could take a long time and the other blocking bugs are done, so I will close this.
