Rust Programming is a systems programming language that focuses on safety, performance, and Consistency. It was first developed by Mozilla and published in 2010. Rust is designed to provide low-level control over system resources without Sacrifice high-level abstraction, creating it suitable for a wide range of applications, including program operating systems, games development, and web site services.

¶1. Key features of Rust Programming:

Here are some of the main features of Rust that make it one of the most popular programming languages in present times.

¶2. Memory Safety:

Rust by eliminating many common programming errors related to memory management, such-as null pointer dereferences, buffer flow, and data raceing , through a system of Ownership, borrowing, and full life. The ownership system make ensures that memory is free correctly and efficiently without relying on a dust collector.

¶3. Concurrency:

Rust has built-in corroboration for concurrent programming, allowing developers to write protected, concurrent code without disquieting about data races. The ownership system plays a crucial role in stopping data races by enforcing appropriate rules on how data can be accessed and temper concurrently.

¶4. Zero-Cost Abstractions:

Rust provides high-level abstractions without incurring a runtime overhead. This means that you can make code at a high level of abstractiveness , similar of languages like Python or Java, but the composed code performs as efficiently as low level, manually to optimize code.

¶5. Borrowing and Lifetimes:

Rust’s taking system allows multiple parts of a program to access data without immolate safety. Lifetimes are vaccine that specify the scope for which mention are valid, helping the compiler ensure that mention do not outlive the data they point.

¶6. Pattern Matching:

Rust has capable pattern matching ability that allow developers to express complex logic concisely. Pattern matching is used for tasks such as to destroy data, matching enums, and mantaining various control flow continuity.

¶7. Cargo:

Rust comes by a package manager called Cargo, which facilitate the process of residence, testing, and leading Rust projects. Cargo also handles dependency management and create it easy to divide and distribute Rust libraries.

¶8. Community and Ecosystem:

Rust has a growing and active community. The ecosystem is extending with the development of study and frameworks, making it so easy for developers to make a wide range of applications.

¶Run Rust Program using an Online Compiler:

Using the online compiler, you can easily test Rust code snippets and get a real life feel for the language. As you make more comfortable with Rust and decided to develop big projects, you make then explore installing Rust locally on your computer.

¶How can Install Rust program on your Computer:

To install after Rust on your computer, you can maintains these common steps. The process may vary highly depending on your operating system.

¶For Windows:

1. Visit the official Rust website: [https://www.rust-lang.org/]
2. Look for the Get Rust button on the homepage and click on it.
3. Download the installer for Windows.
4. Run the installer and follow the on-screen instructions.
5. During the installation, you’ll be prompted to proceed. Accept the default options unless you have specific preferences.
6. Once the installation is complete, open a new command prompt or PowerShell window and type:

$ rustc --version

This command should display the installed Rust version, confirming that the installation was successful.

¶For macOS:

1. Open a terminal.
2. Install Homebrew (if you haven’t already) by following the instructions on the Homebrew website.
3. Once Homebrew is installed, use it to install Rust by running the following command:

brew install rust

4. After the installation is complete, type the following command to verify the installation:

rustc --version

¶For Linux:

1. Open a terminal.
2. Run the following command to download and run the Rust installer:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

3. Follow the on-screen instructions. This will download and install Rust.
4. Once the installation is complete, close and reopen your terminal or run:

source $HOME/.cargo/env

5. Verify the installation by running:

rustc --version

¶Output:

rustc 1.75.0 (2023-12-28)

after get this type of output, the installation is done successfully.

¶First Rust Program:

Now try to write our first Rust program.

Make a file called main.rs on your system and add the following steps. Rust program files finish with a .rs extension.

fn main() {
    println!("Hello, World!");
}

This Rust program prints "Hello, World!" on the screen.

Please Now, open your command terminal and enter the following commands to compile and run your Rust program file.

¶On Windows:-

> rustc main.rs
> ./main.exe
Hello, World!

¶On Linux and MacOS:-

$ rustc main.rs
$ ./main
Hello, World!

Here, - rustc main.rs compiles Rust program - ./main or ./main.exe runs the program

You should see the string "Hello, World!" printed on your command terminal. Congratulations! You’ve just created and run your first Rust program
