This article is about installing the Rust programming language in Linux. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Rust is often referred to as rust-lang. Rust is a universal, multi-paradigm, modern, cross-platform, and open-source systems programming language sponsored by Mozilla Research.

It aims to achieve goals such as security, speed and concurrency.

Rust is syntactically similar to C++, but its designers wanted it to provide better memory security while maintaining performance.

Rust is currently used in many organizations, such as Firefox, Chef, Dropbox, Oracle, GNOME, etc.

How to install Rust in Linux?

There are many ways to install Rust, but here are the official recommendations.

$ curl https://sh.rustup.rs -sSf | shinfo: downloading installer Welcome to Rust! This will download and install the official compiler for the Rust programming language, and its package manager, Cargo. It will add the cargo, rustc, rustup and other commands to Cargo's bin directory, located at: /home/daygeek/.cargo/bin This path will then be added to your PATH environment variable by modifying theprofile files located at: /home/daygeek/.profile /home/daygeek/.bash_profile You can uninstall at any time with rustup self uninstall and these changes willbe reverted. Current installation options: default host triple: x86_64-unknown-linux-gnu default toolchain: stable modify PATH variable: yes 1) Proceed with installation (default)2) Customize installation3) Cancel installation>1 info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'info: latest update on 2018-12-06, rust version 1.31.0 (abe02cefd 2018-12-04)info: downloading component 'rustc' 77.7 MiB / 77.7 MiB (100 %) 1.2 MiB/s ETA: 0 s info: downloading component 'rust-std' 54.2 MiB / 54.2 MiB (100 %) 1.2 MiB/s ETA: 0 s info: downloading component 'cargo' 4.7 MiB / 4.7 MiB (100 %) 1.2 MiB/s ETA: 0 s info: downloading component 'rust-docs' 8.5 MiB / 8.5 MiB (100 %) 1.2 MiB/s ETA: 0 s info: installing component 'rustc'info: installing component 'rust-std'info: installing component 'cargo'info: installing component 'rust-docs'info: default toolchain set to 'stable' stable installed - rustc 1.31.0 (abe02cefd 2018-12-04) 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

Run the following command to configure the current shell.

$ source $HOME/.cargo/env

Run the following command to verify the installed version of Rust.

$ rustc --versionrustc 1.31.0 (abe02cefd 2018-12-04) How to test the Rust programming language?

After installing Rust, follow these steps to check that the Rust language is working properly.

$ mkdir ~/projects$ cd ~/projects$ mkdir hello_world$ cd hello_world

Create a file and add the following code and save it. Ensure that Rust files always end with the.rs extension.

$ vi 2g.rs fn main() { println! ("Hello, It's 2DayGeek.com - Best Linux Practical Blog! ");}

Run the following command to compile rust code.

$ rustc 2g.rs

The above command creates an executable Rust program in the same directory.

$ ls -lhtotal 3.9M-rwxr-xr-x 1 daygeek daygeek 3.9M Dec 14 11:09 2g-rw-r--r-- 1 daygeek daygeek 86 Dec 14 11:09 2g.rs

Run the Rust executable to get output.

$ ./ 2gHello, It's 2DayGeek.com - Best Linux Practical Blog!

All right! It works normally.

Update Rust to version ***.

$ rustup updateinfo: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'info: checking for self-updates stable-x86_64-unknown-linux-gnu unchanged - rustc 1.31.0 (abe02cefd 2018-12-04)

Run the following command to remove the Rust package from the system.

$ rustup self uninstall

After unloading the Rust package, delete the Rust project directory.
