海外TECH	DEV Community	How to start a project in Rust	https://dev.to/vaultree/how-to-start-a-project-in-rust-3g1j	How to start a project in RustRust is a programming language that is becoming more and more popular among developers But what would be the reason for such success The language is basically recognized for its security and performance So if you are new to programming and want to know more about this language created by Mozilla how about reading this content to the end The number of companies interested in Rust developers is growing Just search the job openings for DEVs Vaultree included In addition the language has become popular with DEVs because of its advantages What is Rust In this article I explained why Rust is the most loved programming language In short Rust is a multi paradigm and compiled programming language It was developed by Mozilla Research Its main principles are concurrency without data contention abstraction without overhead and security without garbage collector It can be used in various types of applications such as Command line tools Tools for DevOps Web services Games IoT Internet of Things applications Launched in with open source the language is called like the new clothes C because the two technologies are very similar although Rust is more efficient in terms of security Just out of curiosity Rust is “rust in Portuguese but in general it is not “rusty since it is constantly being updated and is quite competitive in the market How was Rust created Rust began to be developed in Graydon Hoare s leisure time in mid At the time he was working at Mozilla and the company ended up taking an interest in the new language that was similar to C but had more advantages Thus Mozilla decided to invest in the project and gave Hoare a team of technicians to dedicate himself more intensively to the new language Its first version was released in and in a short time it became open source Shortly thereafter Hoare left the technical leadership of the project justifying that he was suffering from burnout a syndrome linked to extreme fatigue and began to dedicate himself to other smaller companies But in mid he accepted a job offer from Apple Inc to work on Swift language development Who uses the Rust language As you have seen the creation of the language was a great achievement for Mozilla which was soon used by many other companies Thus software that is widely used today such as Firefox Dropbox Yelp Firecracker visualisation technology used by Amazon and Cloudflare use Rust But in addition it is present in several projects of companies and startups that seek scalable results prioritising security and performance What makes this language different Did you know that between and the Rust language was considered the preferred language among developers according to Stack Overflow surveys But what explains this predilection Here are some of the benefits of Rust Remember that this does not mean that it is unanimous among developers but it indicates that it is very important to dedicate yourself to study this language to have this differential in your curriculum and belong to this powerful community PerformanceDuring the compilation process Rust itself performs memory management freeing up space until then occupied by variables that are not being used In other languages this function is performed by a garbage collector so Rust demonstrates greater performance as it allows greater speed in development SafetyWhenever a variable is no longer used by the application it is automatically deleted by the language s memory management system This avoids errors and poor performance ProductivityThe developer who chooses Rust gains in productivity Firstly because the language has a very extensive documentation and full of details about its use Secondly because it is able to identify errors that other languages ​​do not thanks to its intelligent compiler UpdatesOne of the advantages is also the constant update which improves the features of the language One of the most recent is from April It has brought improvements to the languages making them easier to read and write In addition the Rust language also runs very well in web applications due to its resourcefulness and high performance giving projects more agility CareerOverall the Rust developer space is hot in the market This is because startups and companies are looking for more agile and secure systems to scale their results Installation and development environmentTo get started with Rust we have two alternatives or using the Play Rust site which is maintained by the Rust core and is a very nice and very complete tool or by downloading the Rustup tool which is the official Rust installer The installation will depend on your operating system but it is very easy on the official website we can find these options mentioned above I will choose the installation because it gives us more options I ll be using VS Code as a code editor the installation is very easy on Windows it s an executable and if you re using a Unix based system I advise you to download it through Snap Below are the extensions that I currently have installed within VS Code Rust Pack this pack contains the main extensions I use Rust Doc Viewer to facilitate documentation For these studies I will be using the stable version of Rust after installing Rustup we run the command rustup default stableThrough this command we set the stable version as default In addition to this we have the option to use the nightly which is updated more frequently with the latest features in the language The stable version is released every months To perform an update and download updates for Rust Cargo and Rustup tools we run the command rustup update stableAnd this way we have an environment ready to start coding Hello WorldIn a directory of your choice we will create a file called hello world rs the rs extension is the Rust file extension Inside this file will be added the following content fn main println Hello World fn→reserved word of the language every function creation within Rust we will use this keyword main →every binary program in Rust has an entry point where the program starts execution every time we run a program this will be the starting point By default this function takes no parameters and returns nothing →function scope everything between the pair of braces is the body scope of this function println →it s a macro we ll see what a macro is in another post but in a nutshell it would be kind of a code template for us to use and the compiler will evaluate it in a pre compile Anything that has a at the end of the command is a macro For better readability as we can see an indentation of spaces was used in this line the Rust style is indenting four spaces not a tab Hello World →Every string inside Rust must be enclosed in double quotes single quotes are used only in the character type This line must be terminated with a semicolon to indicate that this expression has ended and if we have a next one it is ready to start Most lines of Rust code end with a semicolon program executionBefore executing a program in Rust we need to compile it that is generate a file that the computer knows how to execute for that we go through the Unix terminal and enter the directory where we created the file executing the following instruction cd dev workspace rustAnd from the command prompt on Windows cd dev workspace rustThis is the path where I created the file you will change this line by adding the path you created After that let s compile the file by running the command below in the terminal rustc hello world rsInside the directory that the file we created is another one will be generated which will be the executable for Windows it will be a hello world exe and for Unix systems a hello world sh On Windows a file called hello world pbd will also be generated this file contains debugging information To run the file on Windows let s run the command hello world exeTo run the file on Unix let s run the command hello worldThe output will look something like this Hello World So that this post doesn t get too long I ll leave the creation of a Rust project for the next one where we ll start using the Cargo tool Voilà You have your first Rust project In the next article we will talk more in depth about this language and what you can build using it See you About VaultreeVaultree s Encryption in use enables businesses of all sizes to process search and compute fully end to end encrypted
