Rust Introduction 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.

Rust – Introduction

Rust is a systems-level programming language, developed by Graydon Hoare. Mozilla Labs later acquired the program.

Application v/s Systems Programming Languages

Application programming languages like Java/C# are used to build software, which provides 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 −

Why Rust?

Rust focuses on three goals −

The 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.

Performance

Rust programming language does not have a Garbage Collector (GC) by design. This improves the performance at runtime.

Memory safety at compile time

Software built using Rust is safe from memory issues like dangling pointers, buffer overruns, and memory leaks.

Multi-threaded applications

Rust’s ownership and memory safety rules provide concurrency without data races.

Support for Web Assembly (WASM)

Web Assembly helps to execute high computation-intensive algorithms in the browser, on embedded devices, or anywhere else. It runs at the speed of native code. Rust can be compiled to Web Assembly for fast, reliable execution.
