If this is the first time you are using Rust you will have to install Rust on your Windows machine.

To install see this link – https://www.rust-lang.org/tools/install

To install Rust on Windows sybsystem for Linux, use this shell command-

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

Check the version of Rust-

rustup --version

Check the version of Rust compiler

rustc --version

To update the Rust, use following command-

rustup update

Create a main.rs file and add code to print a string

fun main(){
    println!("Hello World!")
}

Compile using rust compiler

rustc main.rs

This should create a pdb and exe file

Execute the main.exe file and this should print the string

Create a Rust project using Cargo

Cargo is a build and package manager.

  • Helps to manage dependecies for repetable builds
  • Downloads and builds external libraries
  • calls rustc with correct parameters
  • Included with standard rustup installation

For creating a new Rust project using Cargo package manager-

cargo new first_rust_prj

Tip – The name of the project should be snake case. Example this will give a warning. Atlhough this will create a project.

cargo new FirstRustPrj //Warning
 
Creating binary (application) `FirstRustPrj` package
warning: the name `FirstRustPrj` is not snake_case or kebab-case which is recommended for package names, consider `firstrustprj`

This should create following folder structure with main.rs and Cargo.toml (configuration) file.

TOML – Tom’s Obvoius Minimal Language.

Alternatively, you can create a project without using Cargo. Create a src directory and create appropriate Cargo.toml namually. To create toml file use init command

cargo init

Building and Running Cargo project

Build the Cargo project using following command-

cargo build

To compile and run directly from the project folder, use following command-

cargo run

Error compiling the project-

error: linker link.exe not found

So the pre-requisite for windows machine is to have MS C++ build tools. Install the smae from here. It should be around 5 GB.

https://visualstudio.microsoft.com/visual-cpp-build-tools

Now this should run the project –

To check the code without producing an executable use follwoing command-

cargo check

Building for Release

Use following command when project is ready for release-

cargo build --release

IDE to develop rust-

Visual Studio Code

Install Visual Studio Code. Then install rust-analyzer for code auto completion, hints and code actions – Link

See here the IDE’s the rust analyser supports.

Rust Rover–

IDE by Jet Brains – here. This is free for non-commercial users.
