Build performance-driven apps with Rust! Explore the fundamentals of hiring the best Rust developers, ensuring memory safety and lightning-fast software.

Since 2016, Rust has ranked as the most loved programming language on Stack Overflow. annual developer survey . In 2020, it was also voted the fifth most searched language.

Created in 2006 by Mozilla employee Graydon Hoare and released at the end of that decade, Rust gained enormous popularity. Mozilla, of course, uses the language, as do companies like Atlassian, Braintree, Coursera, Dropbox, Microsoft, Mozilla, Postmates, Xero, and many others.

Rust is a great option for many projects, but you need the right developer with experience and skills. Here's how to find and hire a talented Rust developer.

What is rust?

Rust is an open source programming language that has a series of qualities such as security and high performance, similar to C++. However, Rust offers some advantages over C++, such as user-friendly syntax and memory management, as well as security without the use of garbage collection. Additional qualities and features include:

Concurrency
No segment failures
Parallelism
Zero-cost abstractions

There are many different applications for Rust, from operating systems to virtual reality (VR), from blockchain to games. Given its popularity, Rust has a huge community that offers a lot of troubleshooting assistance and provides advice and resources for other developers and enthusiasts. There are several frameworks and other tools available to help with the development of the Rust ecosystem as well.

How difficult is it to find a qualified rust developer?

In 2019, GitHub named Rust the second fastest growing language on the site, having increased 235% in usage over the previous year. And, of course, it has the distinction of being the most loved language, as rated by developers on Stack Overflow.

This might suggest that it is relatively easy to find a Rust developer, given its popularity. Unfortunately, it's not that simple.

While many developers are eager to work with Rust, few actually have the necessary experience with the language. The learning curve is quite steep, so it can be a difficult language to master. In fact, some developers describe it as the most complex language to learn in existence.

That’s not to say it’s an impossible task – finding a talented Rust developer is, of course. Because so many developers are excited about the language, there are a good number of people who have tried it and even more who are willing to learn it. There are also some who are already comfortable and skilled in Rust.

What to look for in a Rust developer

Of course, if you're looking for a Rust developer, you probably don't want to limit your search to those who are excited about learning the language – you want someone who has already worked with Rust. That's probably the no. 1 quality on your list. You should also look for developers with experience in other languages, such as Java, C++, Python and others.

A developer with strong teaching skills will also be helpful, so they can educate other team members on how to use this complex language. Interpersonal skills such as problem solving, collaboration, and communication are also beneficial.

Interview Questions

What sets Rust apart from other languages?

Rust combines elements from several other programming languages, although it is not based on any of them, making it a completely unique language in its own right. Memory safety is a defining characteristic of Rust. The language achieves this without garbage collection. It also offers incredibly high performance, readable and easy-to-execute syntax, and much more. Rust is less prone to defects and bugs, making it safer overall.

What are some defining features of Rust?

Rust offers several features, including:

Error management
Error notifications
Guaranteed memory security
Minimum runtime
Move semantics
Pattern matching
Enter security
Zero-cost abstractions

When should you use Rust?

Rust has several applications. Blockchain systems are an example of technology that benefits from language. Many operating systems also use Rust – some are even written in the language, like Redox. Although not one of its main applications, game engines sometimes take advantage of Rust as well. And the backend of web applications is often written in this language as well.

Ultimately, Rust is such a safe and high-performance language that it is used in a wide range of projects, especially those that require these qualities.

When should you use Rust instead of C++ and vice versa?

Rust is often compared to C++. But the two languages diverge on several points. Rust is often used in place of its alternative when memory safety is vital, as well as when you want to avoid undefined behavior. It's also a solid choice if concurrency is a priority. Furthermore, while both languages are quite difficult to learn, Rust is considered the more accessible of the two.

In the meantime, there are some cases where C++ is a better choice. For example, if you want lots of tools like frameworks and libraries to help solve problems, you'll find more options with C++, although Rust has some available. Game development is also a little easier in C++.

What is load?

Cargo is Rust's package manager. Most programs written in Rust take advantage of Cargo. It has several uses, including downloading and handling dependencies, downloading and building libraries, creating packages for distribution, and uploading these packages to the Rust package registry, called crates.io.

Job description
