Fundamentals of Rust

Learn Rust and develop UNIX system utilities and network applications

Mihalis Tsoukalos

Rust is a modern, highly popular, general purpose open source programming language. Rust is not only fast and memory safe, it also supports concurrent programming and offers Cargo, which is the dependency and built-in management tool of Rust.

The purpose of this is course is to introduce you to the Rust programming language using a variety of code examples. You will learn how to write and execute Rust programs and use Cargo. You'll also understand how to use the data types of Rust and create your own structures and Rust packages. The course guides you in writing concurrent applications in Rust, generating random numbers, and organizing your Rust code into packages, along with creating TCP/IP servers and clients and using WebAssembly with Rust.

What you'll learn-and how you can apply it

  • How to work with Rust data types and composite types
  • How to utilize Cargo
  • Develop basic UNIX command-line utilities
  • Develop concurrent applications
  • Use WebAssembly with Rust
  • Develop a TCP server as well as a TCPclient in Rust

This training course is for you because...

The course is aimed at UNIX developers, administrators and web developers with a background in programming languages such as Python, C, C++, Perl, Ruby, and PHP who want to start developing system tools, web and TCP/IP applications in Rust. This course will also be beneficial for those interested in developing command-line utilities and applications that work over networks in Rust.


  • A working UNIX system like Linux and macOS – any UNIX system with a recent Rust installation will do.
  • Basic knowledge of a UNIX shell – the bash shell will be used in this Live Course but you can use any UNIX shell of your choice.

Materials, downloads, or Supplemental Content needed in advance

  • A recent Rust installation
  • A text editor such as vim, Emacs, or TextMate.
