Ferrocene is the main Rust compiler - rustc - but quality managed and qualified for use in automotive and industrial environments (currently by ISO 26262 and IEC 61508) by Ferrous Systems. It operates as a downstream to the Rust project, further increasing its testing and quality on specific platforms. We will publish further detailed blog posts on the components and changes in Ferrocene in the coming weeks.

All changes we made to increase the quality of the Rust compiler have already made it to the main Rust project upstream. See Pietro’s blog post for more details.
