Rust is a programming language that aims at safe concurrency. If you are thinking about the syntax, there is some good news for you.
The syntax for Rust is similar to that of C++. In this piece, you will get the basic guide on how to use Rust as a Windows programming language.
This is the programming language which I shall highly recommend you to use.Thus, If you are interested to work on this programming language, go through the steps given below.
Installing Rust
The first thing you have to do is install rust. To do that visit the installation page. Click on the button which is termed as “Rustup-Init.exe.” Following that, click on this button and your browser will begin to download the “Rustup-Init.exe.”
This installer is significantly a command-line installer. Follow the given instruction to complete the full installation of the package.
The installation of Rust will change the environment of your device. So after the end of the installation of the program, you will require to launch a fresh command prompt for the new changes so that the device gets adapted to it.
A few of the advantages provided by Rustup is that it allows to swap the style of compiler like stable, beta or nightly more easily and is in building for other targets.
You may choose Nightly or Stable but the commands will be available at the terminal. You will require no significant shell to reach them.
The following commands are the Rust compiler and the Rust package installer respectively – ‘rustc’ and ‘cargo’.
After the installation of Visual Studio, Rustup discovers it and will allow you to install the compiler that operates with the VS (Visual Studio) toolchain.
Initially, Rustup will allow you to pick up the compiler and start working by selecting nightly or release.

Check Whether Rust is Installed or Not
Open up a new PowerShell window or command prompt and perform the following: rustup –version
If a version number is noticeable to you, then it is undeniable that the toolchain is firmly installed on your device.
You have to verify that the current version of Rust and all of the other bits of material in the toolchain are arrayed with a command line. The command line is rustup update
Configure VS Code (Virtual Studio Code)
The number of Visual Studio Code (VS Code) is many that support Rust. ‘Rust Extension Pack’ is one of the most demanded in the market.
Also, the specialty about it is it does not only bundles the Rust RLS official extension but also includes the most popular cargo and TOML plugins available. For the installation of this extension pack:
- Navigate to the Extension panel (or what you can do is type Ctrl+Shift+X)
- In the search box type “Rust Extension Pack”.
- For the last step, click on the Install switch.
There is only one insufficiency in the Rust Extension Pack and that is the deficiency of test integration. Rust Test Explorer is a very good solution to this issue.
You will just have to follow the above-given steps to install the extension and you will be fitted of navigating and accomplishing the unit tests from the Test Explorer board.
Writing Rust Code in Windows
Write Rust code for running Rust program as a Windows programming language. Do this task by choosing the Rust support you admire the most and install their Rust plugin or syntax highlighter.
‘Racer’ is the project support that comes up with many of these Rust plugins. This support offers you an autocompletion. Visual Rust can be a point of attraction for the VS (Visual Studio) users.

Create a Simple Hello World Project
In visual studio code, you have to open a new window followed by an empty folder in the window. In the strip of the Explorer, create a new file with the name ‘Cargo.toml’ with the subsequent data:
[package]
name = “hello-world”
version = “0.1.0”
The succeeding thing you need to do is create a brand new record or directory with the name ‘src’. Inside that particular directory, you have to build a file with the title main.rs along with the content given below.
fn main() {
println!(“Hello World!”);
}
Build Up a Build Task
visual studio code will run an inbuilt task every time you choose to develop your code. The built code will get configured to execute the “cargo build” command line every time you will start with this code building procedure.
Press the control key, shift key and P simultaneously on the keyboard to open the command palette. Type in “build” and choose “Tasks: Configure Default Build Task”.
The next job is to pick “Rust: cargo build”.
Following the above instructions will lead you to the creation of a tasks.json file that has only one, built-in developing assignment.
After this every time you press Ctrl+Shift+B keys from the keyboard, virtual Studio code will administer cargo build.
The Contour of the Unit Tests
Code runs a task which is thereby defaulted as same as the build task at the time you opt for executing unit tests.
Take the main.rs file off the latch. Write a simple test (this test should always fail) just under the main function.
#[test]
fn should_fail() {
unimplemented!();
}
You will now save this file. The ensuing task, open the command palette once more. Type “task” in the name text box and pick “Tasks: Configure Default Test task”. After this, you have to select “Rust: cargo test”.
What this will do is append a cargo text assignment to the file tasks.json. From now on the VS Code will run the “cargo test” command every time you will run the Test Task. Also, VS Code will give you feedback in the terminal panel. Run the tests straight up from the Test Explorer if you desire to execute the unit tests from a UI.
Configuration of Error Removal or Debugging
You can get a detailed version of this particular section but I will keep this easy for you. If you want to take full benefits of debugging Rust in Code, you just need to perform these simple steps mentioned below
- You have to install the extension file of C or C++.
- Next, complete the installation of the Native Debug Extension.
- Connect a raw configuration in the debug tapestry.
- Mention the “C++” environment which will manufacture a new launch.json file.
- With the creation of a brand new launch.json file, alter the program value to “${workspaceFolder}/target/debug/hello-world.exe”.
- The final step is saving the file.
Now your VS Code will begin to debug a new specimen from your programs and add breakpoints whenever lacked.
Let’s Wrap Up
Graydon Hoare designed Rust by focusing on the safety measures provided to the users. Rust attained the place for being the most desired programming language in the Stack Overflow Developer Survey back in 2016.
Memory safety with high-level performance is the main characteristic of this programming language.
After all this, there are many scopes through which this language can be developed in many ways.Rust already helps you to create, run and debug applications without a box of complexities.
The team is working on this language as much as possible for the betterment of the experience of the users by the use of Rust on windows.
Follow this facile guide to use rust as a Windows programming language.So let’s wind up for today. I hope this list of steps was quite helpful to you.
