Ferrocene is a safety-critical Rust toolchain, a downstream fork of the official Rust compiler, qualified for use in safety- and mission-critical systems. It is maintained by Ferrous Systems and qualified according to ISO 26262 (ASIL D), IEC 61508, and IEC 62304 standards.

Use cases

• build safety-critical software in Rust for automotive systems
• use Rust in medical devices requiring IEC 62304 compliance
• develop industrial control software with a qualified toolchain
• target bare metal Arm and QNX with Rust
• obtain certification materials for a Rust compiler
• compile Rust for aerospace and railway applications

When to choose

• you need a qualified Rust compiler for functional-safety standards like ISO 26262 or IEC 61508
• you are building safety- or mission-critical embedded systems in Rust
• you need certification documentation, safety manuals, and traceability matrices for a Rust toolchain
• you target QNX, RHIVOS, or bare-metal Arm platforms with Rust

When to avoid

• you just need a standard Rust toolchain for general development - use upstream rustc instead
• you want to contribute compiler changes - those belong upstream in rust-lang/rust
• you need prebuilt binaries without a commercial relationship - they are gated behind customer accounts
• your project has no safety or certification requirements
