| shinfo: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust 
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustuphome directory, located at:


This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory located at:


This can be modified with the CARGO_HOME environment variable.
The cargo, rustc, rustup and other commands will be added toCargo's bin directory, located at:


This path will then be added to your PATH environment variable bymodifying the profile files located at:

 /Users/tinasi/.profile  /Users/tinasi/.zshenv

You can uninstall at any time with rustup self uninstall andthese changes will be reverted.

Current installation options:

 default host triple: x86_64-apple-darwin   
  default toolchain: stable (default)          
     profile: default 
 modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation
  1. Choose the “1) Proceed with installation (default)” option by typing 1. The system starts unpacking the installer.

Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your path environment variable. Next time you log in this will be done automatically.

To configure your current shell, run:
source $HOME/.cargo/env
TinaS-MacBook-Air-2:~ tinasi$ curl --proto '=https' --tlsv1.2 -sSf | sh
  1. The success message – Rust is installed now. Great! Shall be shown.
  2. To verify Rust is installed successfully, use the below command.
TinaS-MacBook-Air-2:~tinasi$ rustc --version
-bash: rustc: command not found
  1. The “command not found” error shall be shown as output.
  2. Before executing the above command, use or type the below first (written in blue). This is to set a path variable.
TinaS-MacBook-Air-2:~ tinasi$ source $HOME/.cargo/env
TinaS-MacBook-Air-2:~ tinasi$ 
  1. Now, verify whether the rust installation is successful or not. Write the text (in blue) below to check the version.

NOTE: “rustc” stands for rust compiler for executing or running any file in Rust.

TinaS-MacBook-Air-2:~ tinasii$ rustc --version
rustc 1.49.0 (e1884a8e3 2020-12-29)
TinaS-MacBook-Air-2:~ tinasi$ 
  1. The command has returned the output with the version of Rust installed on your Mac.

How to Write the First Program in Rust

Rust is similar to C providing more features than C using the libraries available. Here, let us write the first program in Rust to understand how it works.

  1. Open your terminal window.
  2. Write the command below to create your rust file using vim editor.
  1. Paste the code below.
fn main() {    println!("Happy to Write My First Rust Program!");}
3L, 69C
  1. Hit ESCAPE.
  2. Type:wq command to save and exit the file.
  3. Next, type the command. ENTER
  1. You will see the compile success and now to view the output, enter the below command. You will see the output.
$ ./myfirstrustprogram
Happy to Write My First Rust Program!
  1. Yo! You have written your first code in Rust.

Uninstall Rust when not needed

The way we have seen the installation of Rust is so quick and simple. To simply remove Rust from your system, a couple of actions are required.. Let us see how we uninstall Rust.

  1. Come back to the terminal window. (Spotlight search – COMMAND+SPACEBAR, type terminal)
  2. Type the command written in Blue. ENTER.
TinaS-MacBook-Air-2:~ tinasi$ rustup self uninstall

Thanks for hacking in Rust!
This will uninstall all Rust toolchains and data, and remove$HOME/.cargo/bin from your PATH environment variable.
Continue? (y/N) 
  1. To continue, say y.
Continue? (y/N) y
info: removing rustup home
info: removing cargo home
info: removing rustup binaries
info: rustup is uninstalledTinaS-MacBook-Air-2:~ tinasi$ 
  1. You shall see the message for successful uninstallation.
  2. There you go! You are done.
