A linked Safety-Critical Rust guideline may cover all or part of the corresponding external guideline. When coverage is partial, the comment shall identify the covered behavior and material gaps. A blank Safety-Critical Rust rule cell means that no mapping is currently recorded. It does not mean that the external guideline is inapplicable to Rust. Inapplicability shall be stated explicitly with a reason. Categories from the external standard and the Safety-Critical Rust Coding Guidelines are reported independently and need not match. .. toctree:: :maxdepth: 1 cert-c-2016-mapping misra-c-2025-mapping
