What is Rust?

• Rust is a system programming language developed by a Mozilla employee "Graydon Hoare" in 2006. He described this language as a "safe, concurrent and practical language" that supports the functional and imperative paradigm.
• The syntax of rust is similar to the C++ language.
• Rust is free and open source software, i.e., anyone can use the software freely, and the source code is openly shared so that the people can also improve the design of the software.
• Rust is declared as one of the "most loved programming language" in the stack overflow developer survey in 2016, 2017 and 2018.
• There is no direct memory management like calloc or malloc. It means, the memory is managed internally by Rust.

What is the Rust Programming Language Used For?

Rust is a modern computer programming language developed by Mozilla in 2010. It was initially developed to build high-programming applications without the issue of invalid memory access that developers were facing while using C and C++. This system programming language facilitates designing and writing computer programs that allow smooth integration of computer hardware and software. 

The main purpose of using Rust is enhanced safety, speed, and concurrency, or the ability to run multiple computations parallelly. In simple words, Rust is used for three essential purposes in programming; performance, safety, and memory management. Hence, Rust is used to develop advanced applications like gaming engines, operating systems, and browsers that demand scalability.

Why Should You Learn Rust Programming Language?

Rust is an advanced programming language that is beneficial to build tech applications that align with modern Information Technology (IT) architecture requirements. Here are the top four reasons why you should learn Rust:

1. Rust facilitates easy scalability and concurrency and is suitable for building heavy applications to meet the increasing tech demands in the modern world.
2. It uses a logical and functional syntax that allows developers to handle low-level programming for IoT (Internet of Things) applications.
3. The old codes in Rust are compatible with the newer versions of the language.
4. Rust has an asynchronous processing model that allows developers to create and run independent functions, which can be collaborated later.

Features of Rust Programming Language

• Safety and enhanced memory management without having a garbage collector (automatic memory management feature)
• Zero-cost abstraction (a feature that allows developers to hide internal details of the code)
• “Efficient C bindings” which allow developers to integrate Rust and C programming language features
• A unique manual memory management feature that provides control of the allocation and deallocation of memory
• A type interference feature that automatically determines an expression while coding

Advantages of Rust Programming Language

• Reduces data compile time as it provides better concurrency than other programming languages
• Provides low-level control for giving direct programming instructions, despite having a manual memory management feature 
• A friendlier syntax in comparison to C++ and provides better code safety

Disadvantages of Rust Programming Language

• A relatively newer programming language and some of its features are not fully implemented
• Does not support data structures like lists or vectors and is not object-oriented 
• Risk of memory leaks increased by the manual memory management feature in Rust 

Example of Rust Programming Language

Here is an example of Rust code to help you understand Rust better and how it works:

First, you must create a main.rs file after installing Rust on Windows. Once you open the file, enter the below-given code:

fn main() {

 println!(“Hello, world!”);

}

Now, you need to enter the following command on Windows

> rustc main.rs

> .\main.exe

Hello, world!

After the command is complete, you will see “Hello, world!” printed on your screen.
