Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. While Rust is syntactically similar to C++, one thing that it can guarantee is memory safety by using a borrow checker to validate references.
Stack Overflow’s 2020 Developer Survey found that Rust was the most loved programming language among developers for the fifth year in a row, with 86.1 percent of Rust developers saying that they want to continue working with it.
Besides, Rust allows you to store data on the stack or on the heap and determines at compile time when memory is no longer needed and can be cleaned up. This allows efficient usage of memory as well as more performant memory access.
The advantages of Rust mean that other big tech companies, such as Dropbox, Figma, Discord and Coursera, are already starting to use it internally. While it may be a bit more difficult to master than other beginner languages, Rust programming skills are likely to pay off handsomely, as the language’s popularity will only continue to rise in the near future.
- Better memory safety due to the compiler
- Easier concurrency due to the data ownership model that prevents data races
- Zero-cost abstractions
