Rust<\/strong>\u00a0(commonly known as\u00a0Rust-Lang<\/strong>) is a relatively new, open source practical systems programming language that runs extremely fast, prevents segfaults, and guarantees thread safety. It is a safe and concurrent language developed by\u00a0Mozilla<\/strong>\u00a0and backed by\u00a0LLVM<\/strong>.<\/p>\n

It supports zero-cost abstractions, move semantics, guaranteed memory safety, threads without data races, trait-based generics and pattern matching. It also supports type inference, minimal runtime as well as efficient C bindings.<\/p>\n

Rust<\/strong>\u00a0can run on a great number of platforms and is being used in production by companies\/organizations such as\u00a0Dropbox<\/strong>,\u00a0CoreOS<\/strong>,\u00a0NPM<\/strong>\u00a0and many more.<\/p>\n

In this article, we will show how to install\u00a0Rust<\/strong>\u00a0programming language in Linux and setup your system to get started with writing programs with rust.<\/p>\n

Install Rust Programming Language in Linux<\/h3>\n

To install\u00a0Rust<\/strong>, use the following official method of installing rust via the\u00a0installer-script<\/strong>, which requires\u00a0curl command-line downloader<\/a>\u00a0as shown.<\/p>\n

$ sudo apt-get install curl  [On Debian\/Ubuntu<\/strong>]\r\n# yum install install curl   [On CentOS\/RHEL<\/strong>]\r\n# dnf install curl           [On Fedora<\/strong>]\r\n<\/pre>\n
Then install rust by running the following command in your terminal, and follow the onscreen instructions. Note that rust is actually installed as well as managed by the rustup tool.<\/p>\n
$ curl https:\/\/sh.rustup.rs -sSf | sh\r\n<\/pre>\n
\n
\"Install<\/a><\/p>\n

Once the\u00a0Rust<\/strong>\u00a0installation is complete, the Cargo\u2019s bin directory (~\/.cargo\/bin<\/code>\u00a0\u2013 where all tools are installed) will be added in your\u00a0PATH<\/strong>\u00a0environment variable, in\u00a0~\/.profile<\/code>.<\/p>\n
During the installation\u00a0rustup<\/strong>\u00a0will attempt to add the cargo\u2019s bin directory to your\u00a0PATH<\/strong>; if this fails for one reason or another, do it manually to get started with using rust.<\/p>\n

\"Add<\/a><\/p>\n

Next, source the\u00a0~\/.profile<\/code>\u00a0file to use the modified\u00a0PATH<\/strong>\u00a0and configure your current shell to work with the rust environment by running these commands.<\/p>\n
$ source ~\/.profile\r\n$ source ~\/.cargo\/env\r\n<\/pre>\n
Finally verify the version of\u00a0rust<\/strong>\u00a0installed on your system by running the following command.<\/p>\n
$ rustc --version\r\n<\/pre>\n
\n
\"Check<\/a><\/p>\n

Test Rust Programming Language in Linux<\/h3>\n
Now that you have\u00a0rust<\/strong>\u00a0installed on your system, you can test it by creating your first rust program as follows. Begin by making a directory where your program files will reside.<\/p>\n
$ mkdir myprog\r\n$ cd myprog\r\n<\/pre>\n
Create a file called\u00a0test.rs<\/code>, copy and paste the following lines of code to the file.<\/p>\n
fn main() {\r\n    println!(\"Hello World, it\u2019s TecMint.com \u2013 Best Linux HowTos, Guides on the Internet!\");\r\n}\r\n<\/pre>\n
Then run the following command which will create an executable called\u00a0test<\/code>\u00a0in the current directory.<\/p>\n
$ rustc main.rs\r\n<\/pre>\n
Finally, execute\u00a0test<\/code>\u00a0as shown.<\/p>\n
$ .\/test \r\n<\/pre>\n
