Install Rust
Using rustup (Recommended)
It looks like you’re running macOS, Linux, or another Unix-like OS. To download Rustup and install Rust, run the following in your terminal, then follow the on-screen instructions. See “Other Installation Methods” if you are on Windows.
curl –proto '=https' –tlsv1.2 -sSf https://sh.rustup.rs | sh
Notes about Rust installation
Getting started
If you're just getting started with Rust and would like a more detailed walk-through, see our getting started page.
Toolchain management with rustup
Rust is installed and managed by the rustup tool. Rust has a 6-week rapid release process and supports a great number of platforms, so there are many builds of Rust available at any time. rustup manages these builds in a consistent way on every platform that Rust supports, enabling installation of Rust from the beta and nightly release channels as well as support for additional cross-compilation targets.
If you've installed rustup in the past, you can update your installation by running rustup update.
For more information see the rustup documentation.
Configuring the PATH environment variable In the Rust development environment, all tools are installed to the ~/.cargo/bin directory, and this is where you will find the Rust toolchain, including rustc, cargo, and rustup.
Accordingly, it is customary for Rust developers to include this directory in their PATH environment variable. During installation rustup will attempt to configure the PATH. Because of differences between platforms, command shells, and bugs in rustup, the modifications to PATH may not take effect until the console is restarted, or the user is logged out, or it may not succeed at all.
If, after installation, running rustc –version in the console fails, this is the most likely reason.
Uninstall Rust
If at any point you would like to uninstall Rust, you can run rustup self uninstall. We'll miss you though!
Other installation methods The installation described above, via rustup, is the preferred way to install Rust for most developers. However, Rust can be installed via other methods as well.

info: downloading installer
Welcome to Rust!
This will download and install the official compiler for the Rust programming language, and its Rust package manager, Cargo.
Rustup metadata and Rust toolchains will be installed into the Rustup home directory, located at:
/home/USERNAME/.rustup
This can be modified with the RUSTUP_HOME environment variable.
The Cargo home directory is located at:
/home/USERNAME/.cargo
This can be modified with the CARGO_HOME environment variable.
The cargo, rustc, rustup and other Rust commands will be added to Cargo's bin directory, located at:
/home/bowman/.cargo/bin
This path will then be added to your PATH environment variable by modifying the profile files located at:
You can uninstall at any time with rustup self uninstall and these changes will be reverted.
Current installation options:
default host triple: x86_64-unknown-linux-gnu
default toolchain: stable (default)
profile: default
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

I'm going to ask you the value of each of these installation options.
You may simply press the Enter key to leave unchanged.
Default host triple? [x86_64-unknown-linux-gnu]
Default toolchain? (stable/beta/nightly/none) [stable]
Profile (which tools and data to install)? (minimal/default/complete) [default] complete
Modify PATH variable? (Y/n)
Y
Current installation options:
default host triple: x86_64-unknown-linux-gnu
default toolchain: stable
profile: complete
modify PATH variable: yes
1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!
To get started you may need to restart your current shell. This would reload your PATH environment variable to include Cargo's bin directory ($HOME/.cargo/bin).
To configure your current shell, run:
source “$HOME/.cargo/env”

- Snippet from Wikipedia: Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron.
Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron, unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust".
Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of reactions between iron and chloride in an environment deprived of oxygen. Rebar used in underwater concrete pillars, which generates green rust, is an example. Although rusting is generally a negative aspect of iron, a particular form of rusting, known as stable rust, causes the object to have a thin coating of rust over the top. If kept in low relative humidity, it makes the "stable" layer protective to the iron below, but not to the extent of other oxides such as aluminium oxide on aluminium.
