The Rust programming language offers the rare and valuable combination of statically verified memory safety and low-level control. Imagine C++ but without dangling pointers, null pointer dereferences, or buffer overruns, and with a deep library of freely reusable libraries. This practical guide gives systems and application programmers alike a solid understanding of Rust’s rules, and shows how to put them to work ensuring their programs are not only efficient, but free of broad classes of common errors.
