Rust Essentials. A quick guide to writing fast, safe, and concurrent systems and applications - Second Edition

Rust is the new, open source, fast, and safe systems programming language for the 21st century, developed at Mozilla Research, and with a steadily growing community. It was created to solve the dilemma between high-level, slow code with minimal control over the system, and low-level, fast code with maximum system control.

• It is no longer necessary to learn C/C++ to develop resource intensive and low-level systems applications.

• You'll install Rust and learn how to work with its package manager Cargo.

This book will give you a head start to solve systems programming and application tasks with Rust.We start off with an argumentation of Rust's unique place in today's landscape of programming languages. The various concepts are introduced step by step: variables, types, functions, and control structures to lay the groundwork.

• Next we look at Rust's specific way of error handling, and the overall importance of traits in Rust code.
• The pillar of memory safety is treated in depth as we explore the various pointer kinds.

Then we explore more structured data such as strings, arrays, and enums, and you’ll see how pattern matching works.Throughout all this, we stress the unique ways of reasoning that the Rust compiler uses to produce safe code. Next, you’ll see how macros can simplify code generation, and how to compose bigger projects with modules and crates.

Finally, you’ll discover how we can write safe concurrent code in Rust and interface with C programs, get a view of the Rust ecosystem, and explore the use of the standard library.
