Linux kernel now accepts Rust modules (started 2022), and projects like Servo (Mozilla's browser engine) and Firecracker (AWS) use Rust for new components. However, C's 50+ year dominance means it will remain ubiquitous for decades. Rust is best suited for new systems projects, while C maintains legacy systems and embedded platforms."},{"question":"Can Rust achieve C's portability?","answer":"Largely yes, but with caveats. Rust compiles to most platforms C supports (x86, ARM, WebAssembly, MIPS), but C has decades more platform coverage for obscure architectures and older systems. For modern systems (Linux, Windows, macOS, mobile), Rust achieves near-identical portability with the benefit of safety."},{"question":"Why is Rust compilation so slow?","answer":"Rust performs extensive compile-time analysis: borrow checking, type inference, and monomorphization (generating specialized code for generic types). This prevents runtime errors but adds 10-100x compilation overhead compared to C. Incremental compilation and parallel builds help, but are not as fast as C's simpler compilation model."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/c-language-vs-rust)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/c-language-vs-rust)), C is a lightweight, decades-old imperative language with minimal overhead and near-universal platform support, while Rust is a modern systems language that enforces memory safety at compile-time witho","dateModified":"2026-07-08T14:07:51.786Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/c-language-vs-rust)","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/c-language-vs-rust)","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/c-language-vs-rust)","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/c-language-vs-rust)#claimreview","url":"https://www.aversusb.net/compare/c-language-vs-rust)","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"C vs Rust Programming Languages","reviewBody":"C is a lightweight, decades-old imperative language with minimal overhead and near-universal platform support, while Rust is a modern systems language that enforces memory safety at compile-time without garbage collection, preventing entire classes of bugs that plague C programs.","datePublished":"2026-07-08T14:07:51.281Z","dateModified":"2026-07-08T14:07:51.786Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/c-language-vs-rust)","url":"https://www.aversusb.net/compare/c-language-vs-rust)","name":"C vs Rust Programming Languages","inLanguage":"en-US"}}}
