Product Description

This practical book introduces systems programmers to Rust, the new and cutting-edge language thats still in the experimental/lab stage. Youll learn how Rust offers the rare and valuable combination of statically verified memory safety and low-level controlimagine C++, but without dangling pointers, null pointer dereferences, leaks, or buffer overruns.Author Jim Blandythe maintainer of GNU Emacs and GNU Guiledemonstrates how Rust has the potential to be the first usable programming language that brings the benefits of an expressive modern type system to systems programming. Rusts rules for borrowing, mutability, ownership, and moves versus copies will be unfamiliar to most systems programmers, but theyre key to Rusts unique advantages.This book presents Rusts rules clearly and economically; elaborates on their consequences; and shows you how to express the programs you want to write in terms that Rust can prove are free of broad classes of everyday errors.
