Rust's Type Checker Implementation Is Unsound: An Empirical Study
An empirical study reveals soundness bugs in Rust's type checker, affecting memory safety and type checking. Key findings highlight critical issues.
Rust is touted as a type-sound language that prevents various undesirable behaviors, including memory bugs. However, the official Rust compiler, rustc, is not free from defects; it contains soundness bugs that allow programs to pass type checks that should fail. This study analyzes 30 reported soundness bugs from GitHub, focusing on their features, symptoms, and community consensus.
