Zig vs. Rust: A Deep Dive into Memory Safety

This article delves into a detailed comparison of Zig and Rust regarding memory safety. Rust, with its powerful compile-time proof system, virtually eliminates memory safety vulnerabilities. While Zig improves upon C with features like slice types and bounds checking, it remains susceptible to memory safety issues such as use-after-free and buffer overflows. The author uses personal experience and project data to demonstrate Rust's memory safety advantage in large projects, but also suggests Zig's potential use in specific scenarios, such as within Wasm sandboxes. Zig's future success may hinge on the development of inexpensive runtime mitigations.
