What is Rust Language?

Rust is a programming language developed by Mozilla that focuses on security and concurrency . The Rust language is jointly developed by the leader of the web language, Brendan Eich, Dave Herman, and Graydon Hoare of Mozilla . Rust is an excellent language for security, concurrency, and utility, for multi-core systems and absorbs important features of other dynamic languages such as : it doesnt need to manage memory, without Null Pointers, and so on . The Rust's syntax is similar to that of C++ . Rust is free open source software that is freely available to anyone and publicly shared so that people can also improve the design of the software .

The great feature of Rust language is the Security .

The Feature of Rust

1. Rust uses the abstract functionality without affecting the runtime performance of the code
2. Rust's error messages are clear and easy to understand, appear in a neat, color-coded format, and suggest spell checking in the program .
3. Rust provides data-type checking functionality, which means it can automatically determine the type of an expression .
4. Rust language can replace a copy operation with a move operation .
5. Rust provides thread functionality without data contention .
6. Rust uses the match pattern to better manage the program's control flow .
7. Rust guarantees memory security by using the concept of ownership .
8. Rust language can communicate with c language easily .
9. Rust programmers can clearly control the memory allocation in release of memory locations and time .

Install Rust

(1) Install C++ Build Tools Before you install Rust, you must install C++ Build Tools .

1. Click the following link to download C++ Build Tools :
2. https : //visualstudio . microsoft . com/downloads/#build-tools-for-visual-studio-2017
3. You can find :

1. Click Download button on the right side, start downloading .
2. After downloading the Build Toos installer, please install Build Tools for Visual Studio 2017
3. During installation, select options that relate to C++ to install .
4. After the installation is complete, please restart the computer .

(2) Install Rust If you have already installed Build Toos, then continue to install Rust . rust-lang . org/tools/install

• Please download the Rust installer RUSTUP-INIT.EXE .
• After downloading the rustup-init.exe installer, please double click it to install Rust .
• You can see the following message :

1. Type , press Enter key to install Rust .
2. When the installation is complete, please press Enter key to confirm .
(3) Rust Test Test Rust to check if the installation is successful . org/tools/install
• Please download the Rust installer RUSTUP-INIT.EXE .
• After downloading the rustup-init.exe installer, please double click it to install Rust .
• You can see the following message :

1. Type , press Enter key to install Rust .
2. When the installation is complete, please press Enter key to confirm .
(3) Rust Test Test Rust to check if the installation is successful .

The Rust working folder is C: \Users\Your_Name. For example, my Rust working folder is C: \Users\RAY. Rust working folder always includes three sub-folders : (1) . rustup folder, (2) . multirust folder, (3) . cargo folder .

Now we need to go to working folder first, and test Rust program . Please run cmd command, open the command line editor .

1. Type cd\ to move to the root directory .
2. Type cd \Users\Your_Name to move to the working folder .
3. Run rustc --version command, you can see the output :
Congratulation ! The Rust installation is successful ! Note: In different Windows OS, the working folder is different . For example, your working folder may be C : \Users\Admin . Then you must find out the folder that contains three sub-folders . rustup folder, . multirust folder, . cargo folder) . cargo folder) .

And make sure this folder as a working folder .

The First Rust Program

Please open the Notepad, and write the following code : Example 1.1

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

Save the file as hello . rs in the working folder, using . rs as extension name . Run cmd command, open the command line editor . Output: Hello, world ! Explanation: fn main( ) defines a function named main . println ! () is a command used to output content . println ! () is a command used to output content .

The extension name of Rust file is . rs . Each statement ends with a semicolon ; cd\ moves to root directory . C : \>cd \Users\RAY moves to my working folder . rustc hello.rs compiles the Rust file hello . exe program .
