The Rust Core Library (libcore) forms the essential, dependency‑free foundation of the Rust Standard Library. Acting as the portable interface between the Rust language and its higher‑level libraries, it defines the intrinsic operations and primitive building blocks that underpin all Rust programs. True to its minimal design, it links against no other libraries—no external crates, no system libraries, and no libc.

For teams requiring formal qualification of libcore, Validas offers a comprehensive libcore Qualification Kit designed to support that process end‑to‑end.

Our Compliance and Safety Framework (COSAFE) aligns requirements from leading standards such as ISO 26262, IEC 61508, and others.

With a dedicated libcore Qualification Package, COSAFE becomes a complete Qualification Kit for the Rust Core Library, enabling compliant and reliable system-level operations in Rust.
