Why Rust? 

Original Post from Stack Overflow:  what is rust and why is it so popular

Rust has been Stack Overflow’s most loved language for four years in a row, indicating that many of those who have had the opportunity to use Rust have fallen in love with it. However, the roughly 97% of survey respondents who haven’t used Rust may wonder, “What’s the deal with Rust?”

• Rust’s static typing does its best to get out of the programmer’s way while encouraging long-term maintainability.
• Rust gives you the choice of storing data on the stack or the heap and determines at compile time when memory is no longer needed and can be cleaned up.
• The biggest benefit Rust can provide compared to these languages is the borrow checker.
• The Rust experience is larger than a language specification and a compiler; many aspects of creating and maintaining production-quality software are treated as first-class citizens.
