What is Rust?

Rust is a programming language that was born to allow you to write code as fast as C or C++, eliminating the drawbacks with the garbage collector to avoid the problems arising from memory management. This was all thanks to Mozilla, but it has worked so well that many people are using it for many programs.

Currently, Rust is funded by large entities such as Amazon AWS, Microsoft Azure, Google Cloud, Facebook, and, since its inception, Mozilla Firefox. But it is also supported by a large community of users who share their experiences and help those new to the language.

As we know, Rust is quite fast, supports object-oriented programming, and is multi-purpose. So all in all it is an important programming language in our time.

So, let’s go for it.

Install Rust on Debian 11

From the Rust website, we are informed of a very simple installation procedure. This is due to the presence of an installation script that makes everything very easy.

So to start the process, you have to upgrade the operating system completely.

sudo apt update
sudo apt upgrade

The download of this script will be done using curl so it has to be installed on the system.

sudo apt install curl

If you do not have the build-essential package installed, you need to do so.

sudo apt install build-essential

Now all you have to do is run the following command:

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

During the installation process, you will be asked how the installation will be performed. In this case, it is wise to choose option 1 which will install Rust with the default configuration.

When the process finishes, you will be prompted to run a command to update the system environment variables. This will allow us to use Rust commands from any location in the terminal.

source $HOME/.cargo/env

And you can also check the compiler version.

rustc --version
rustc 1.54.0 (a178d0322 2021-07-26)

Testing the Rust installation

When we install Rust, we also install cargo which is the Rust package manager and provides us with the command line tools to create our project without any problems.

So, we create our project by executing the following command

cargo new [project-name]

For example

cargo new osradar
     Created binary (application) `osradar` package

This will create a new folder called osradar which will have a file called Cargo.toml where you can specify your project dependencies and manifest. Also, there will be a folder called src where the source code for the application will be. This folder comes with a file called main.rs which is the main file where we will start our coding.

Now access the folder and run the Hello World that comes with the cargo new command.

cd osradar
cargo run

Output:

    Finished dev [unoptimized + debuginfo] target(s) in 0.00s
     Running `target/debug/osradar`
Hello, world!

So, Rust is installed correctly.

Conclusion

Rust is a modern programming language that presents an alternative to C++ and can be used in many places and for many things. Installing it on Debian 11 is something we can do without much difficulty as we have explained.

Rust is an open source, multipurpose and new programming language that aims to retire to the C language. Although it is sponsored by Mozilla and Samsung, it is a community project. Its focus is primarily on large programs that run on the client and server side.

The main characteristics of Rust are performance, reliability, and productivity. Rust can compile and create applications very quickly; it is conducive to very few failures and its large documentation makes it possible to learn quickly.

Install Rust Programming Language on Fedora 34

The installation is quite simple to perform through the terminal. To do this, first, make sure that the distribution is up to date.

So, open a terminal and run

sudo dnf update

After that you should install the development and build tools for this our post will help you.

After that, you can install the curl and nano packages with which we can complete the post.

sudo dnf install nano curl

Now proceed to download and run the installation script provided by the Rust developers.

curl https://sh.rustup.rs -sSf | sh

During the execution of the script, we will be asked about the type of installation. In this case, choose option 1.

Then the whole installation process will continue and at the end, you will see the following screen:

This way the installation has been completed successfully. To make Rust available from the terminal without any problems run

source $HOME/.cargo/env

Now we are ready to try Rust. We are ready to test Rust, for example, show the installed version.

rustc --version
rustc 1.53.0 (53cb7b09b 2021-06-17)

Your first program with Rustc

Now to check that everything is OK we need to create a program. We will do the classic “Hello World”.

First, create the necessary directory structure and access it.

mkdir ~/projects
cd projects
mkdir example
cd example

Obviously, you can change the names and adjust them to your preferences.

Now create the code file

nano helloworld.rs

And add the following code:

fn main() {
println!("Hello, thanks for visiting Osradar blog.");
}

Save the changes and close the editor.

Now compile the program

rustc helloworld.rs

And run it

./helloworld
Hello, thanks for visiting Osradar blog.

So, Rust is installed.

Conclusion

Installing the Rust language in Linux is a fairly simple process. The possibilities offered by this language are many. It is also a great alternative to traditional programming languages.

We already know that in Linux we have many different tools. One of them is the term that has proven to be a great help in many tasks such as downloading files and editing text.

This time we have a terminal tool created with Rust called Ox. Ox is a code editor with a terminal interface that consumes few resources and can help a lot with programming.

Says the program’s developer:

OX IS A CODE EDITOR. IT WAS WRITTEN IN RUST USING ANSI ESCAPE SEQUENCES. IT ASSISTS DEVELOPERS WITH PROGRAMMING BY PROVIDING SEVERAL TOOLS TO SPEED UP AND MAKE PROGRAMMING EASIER AND A REFRESHING ALTERNATIVE TO HEAVILY BLOATED AND RESOURCE HUNGRY EDITORS

Therefore, we can install it on any computer, including the oldest ones.

On the other hand, Ox takes many advantages from applications like Vi, Nano, Emacs, and other veteran programs. All this without dependencies and making it quite light and easy to compile. So few that this is the entire list:

• Rust language
• Termion
• Unicode-rs
• Clap
• Regex
• Rum
• Serde
• Shellexpand

So, let us install it.

Install Ox on OpenSUSE 15.2

Ox is built in the Rust language so we need to install it first.

How to install Rust on OpenSUSE 15.2?

After that, you can start installing the application by running the following command

cargo install --git https://github.com/curlpipe/ox

This will start the whole process of downloading dependencies. When finished, you can invoke the editor with the ox command.

First steps with Ox

When the program is properly installed you can run it from the terminal

ox

Also, you can open a file or specify the path where you want the new file to be created

ox /path/file

There you can start editing code. If you want to save changes, you can do it with the key combination CTRL + S but if it’s the first time you modify the file, you have to choose a name with CTRL + w

Also, you can open a new tab by pressing the CTRL + N

So, you can navigate between tabs with the CTRL + H and CTRL + D keys, and as you can see it’s quite easy to use.

Conclusion

Ox has a long way to go, that’s true, but it’s also an interesting project that adds more functionalities every day and allows us to edit code from the terminal, being easy to use. This gives even more power to the terminal and gives us solutions in multiple environments.

The main characteristics of Rust are performance, reliability, and productivity. Rust can compile and create applications very quickly; it is conducive to very few failures and its large documentation makes it possible to learn quickly.

Install Rust on OpenSUSE 15.2

Perhaps the best way to get Rust on OpenSUSE is through the official installer provided by the language. In this respect, this guarantees that we are running the latest version available and is not complicated.

To do this, open a terminal or connect via SSH and update OpenSUSE.

sudo zypper up

After this, make sure you have the curl package installed on the system

sudo zypper in curl

And all you have to do is run this command which will download and install Rust on your system

curl https://sh.rustup.rs -sSf | sh

During the installation, you will be asked how to install it. It is recommended that you use the default configuration by choosing option 1.

At the end you will get an output screen similar to this one:

And to make rust available in the terminal without problems, run:

source $HOME/.cargo/env

Finally, you can check the version we just installed.

rustc --version
rustc 1.50.0 (cb75ad5db 2021-02-10)

Testing Rust on OpenSUSE 15.2

Now it is necessary to make a test file and run it to make sure that everything is OK.

So, create the project folder and inside it the program folder. You can choose any name you want.

mkdir ~/projects
cd projects
mkdir example
cd example

Now we just need to add some rust code to the file. A hello world!! will suffice.

nano helloworld.rs

And add the following:

fn main() {
    println!("Hello, thanks for visiting Osradar blog.");
}

Save your changes and close the editor.

Then, compile the file with the rustc command

rustc helloworld.rs

And now run it

./helloworld

Finally, you get the following output, which indicates that Rust is now working properly.

Hello, thanks for visit Osradar blog.

So, enjoy it.

To monitor the processes and the memory of your computer, there are tools such as top and htop, however, Hegemon is presented as a modular alternative to them. It is also written in Rust, which guarantees that its consumption will be very fair.

Some of its features are:

• Monitor CPU and memory usage, temperatures, and fan speeds.
• Expand any data stream to reveal a more detailed graph and additional information Adjustable update interval.
• Clean MVC architecture with good code quality.
• Unit tests.

For now, it only supports Linux, but in the future, the development team has in mind to include support for Mac OS and BSD.

So, let’s install Hegemon.

1. Install Rust Language

Hegemon is a tool built in Rust. Therefore, you must install it and configure it properly in order to run it.

We recently taught you how to do it, so there won’t be any problems.

2. Install Hegemon

One of the dependencies is Rust, but when its installation is complete, it is now necessary to install the system’s sensors. With this, Hegemon will be able to measure the temperature of your processors and show information closer to reality.

For RHEL and CentOS:

:~# yum install lm_sensors-devel

If you use Fedora:

:~$ sudo dnf install lm_sensors-devel7

In case you are using Debian, Ubuntu and Linux Mint.

:~$ sudo apt install libsensors4-dev

Now using the Rust cargo package manager, you can install Hegemon without problems.

:~$ cargo install hegemon

Then, run it.

:~$ hegemon

And you will see.

As you can see in the image, you can expand the information shown by pressing the space keyboard. In addition, you can change the default monitoring frequency to 3.

To exit, press q.

Conclusion

While Hegemon is at an early stage of development, the fact that it is modular makes it interesting. In other words, you can expand its functionality on your own. Being programmed in Rust gives us the opportunity to have a good tool without sacrificing resources.
