Rust is a versatile programming language that caters to a wide range of users due to its unique features and capabilities.
Teams of Developers
Rust serves as a productive tool for collaboration among large teams of developers, especially those with varying levels of systems programming knowledge. The language's compiler plays a gatekeeper role, refusing to compile code with subtle bugs, including concurrency bugs. This allows the team to focus on the program’s logic rather than chasing down bugs.
Rust also brings contemporary developer tools to the systems programming world. These include:
- Cargo: The included dependency manager and build tool, which makes adding, compiling, and managing dependencies painless and consistent across the Rust ecosystem.
- Rustfmt: A formatting tool that ensures a consistent coding style across developers.
- Rust Language Server: Powers Integrated Development Environment (IDE) integration for code completion and inline error messages.
By using these and other tools in the Rust ecosystem, developers can be productive while writing systems-level code.
Students
Rust is an excellent choice for students and those interested in learning about systems concepts. Many have used Rust to learn about topics like operating systems development. The Rust community is very welcoming and happy to answer student questions, making systems concepts more accessible to more people, especially those new to programming.
Companies
Hundreds of companies, both large and small, use Rust in production for a variety of tasks. These include command line tools, web services, DevOps tooling, embedded devices, audio and video analysis and transcoding, cryptocurrencies, bioinformatics, search engines, Internet of Things applications, machine learning, and even major parts of the Firefox web browser.
Open Source Developers
Rust is also for people who want to contribute to the Rust programming language, community, developer tools, and libraries. The Rust community welcomes contributions from everyone.
People Who Value Speed and Stability
Rust is for people who crave speed and stability in a language. By speed, we mean both the execution speed of Rust code and the speed at which Rust lets you write programs. The Rust compiler’s checks ensure stability through feature additions and refactoring. Rust strives for zero-cost abstractions, where higher-level features compile to lower-level code as fast as code written manually, making safe code be fast code as well.
