Rust is a modern systems programming language developed by the Mozilla Corporation. It is intended to be a language for highly concurrent and highly secure systems. It compiles to native code; hence, it is blazingly fast like C and C++. This tutorial adopts a simple and practical approach to describe the concepts of Rust programming. This tutorial has been prepared for beginners to help them understand the basic and advanced concepts of Rust. Application programming languages like Java/C# are used to build software, which provide services to the user directly. They help us build business applications like spreadsheets, word processors, web applications or mobile applications. Systems programming languages like C/C++ are used to build software and software platforms. They can be used to build operating systems, game engines, compilers, etc. These programming languages require a great degree of hardware interaction. Systems and application programming languages face two major problems − - It is difficult to write secure code. - It is difficult to write multi-threaded code. The Rust language was designed for developing highly reliable and fast software in a simple way. Rust can be used to write high-level programs down to hardware-specific programs.
