Ferrocene is a toolchain to enable the use of the Rust programming language in safety-critical environments. It is a proper downstream of the main Rust compiler - rustc, maintained by the Rust project on rust-lang/rust.

The mission of Ferrocene is to bring open source practices to safety-critical industries and improve the Rust open source ecosystem through safety-critical practices.

Ferrocene is maintained and supported by the world-renowed experts at Ferrous Systems. Both standard and long-term support are available. Check our website for details.

Ferrocene is qualified for ISO 26262 (ASIL D) and IEC 61508 (SIL 4). Qualification for other standards and areas, such as railway and aerospace, are planned.

Prebuilt Ferrocene binaries are available for customers and partners. You can visit releases.ferrocene.dev to download the release archives after logging in with your Ferrocene account.

The documentation of the Ferrocene toolchain and its source can be found in the ferrocene/doc directory. The documentation contains the projects procedures, its quality management measures and current testing coverage.

Rendered versions of the documentation are also available:

• docs.ferrocene.dev: available to customers and partners, contains the documentation for all release channels.
• public-docs.ferrocene.dev/main: publicly available, contains the documentation for the latest commit merged on the main branch.

Multiple levels of support are available for paying customers, provided by Ferrous Systems. You can log into customers.ferrocene.dev to learn about your support plan, and how to send support requests.

As a downstream of the Rust project, Ferrocene prefers to keep the compiler unmodified. This means that general contributions to the compiler or its tools (and discussions) should happen upstream (rust-lang/rust). However, Ferrocene does serve as a community of peers to propose and produce changes useful in safety-critical changes towards the project.

Contributions to qualification activities and manuals are welcome, but generally gated. Contribution is open to industry and academic partners, customers, and project employees.

You can use the Ferrocene issue tracker to file an issue for the materials provided by the Ferrocene developers. Please note that the issue tracker is not a support channel.

Please note that Ferrocene is governed under the Apache-2.0 license and contribution policies apply to the issue tracker as well as the codebase itself.

Ferrous Systems provides services built and tailored around Ferrocene:

• Trainings: trainings on Rust and Ferrocene, particularly for teams, are available. Trainings can be custom tailored to your needs. Check out our training offerings.

• Inclusion in SDKs: Ferrocene is available to be integrated in your toolchain! Please get in touch to learn more.

• Tailoring, enabling and integration within your system: We're more than happy to enable Rust support in your operating system or tool, including porting the Rust compiler to the targets you need and qualifying them in Ferrocene. Get in touch to learn more.

• Infrastructure support: Ferrocene is built for a DevOps world. Rust for your builds in the cloud is a first-class citizen for us, and we can provide support tailored to you. Get in touch for more information.
