Rust

The new Rust programming language is designed to solve problems with operating systems and fix issues with C and other languages.

In some ways, Rust is an upside down systems programming language. The developers have mostly hunted through old languages to find ideas useful to solve problems software developers face today and mostly ignored recent research into programming languages. Yet Rust solves many key weaknesses of C, C++, and other languages. Rust 1.0, the first stable version of the language, was released on May 15, 2015.

What Makes Rust Special?

To solve key programming-related problems in low level C and C++ languages, ownership is the primary concern of Rust. Ownership helps solve critical security and runtime problems with memory management C and C++ programmers have dealt with for decades.

If you don’t know, low level languages run as close as possible to the native binary 1s and 0s used by your computer to run software. Low level languages are faster than langugaes which need extra runtime software included with their applications to convert their code to a lower level native language. C and C++ are low level languages. Python, Java, PHP, and other languages are higher level languages.

The idea of ownership is fairly simple to explain. When you write code, the programming language assigns your code to specific parts of your computer memory and indexes its location. The index makes it easy to find, process (compile), and run your code. With some languages like C and C++, it is possible for the programming language to become confused about where your code resides in memory. Connections within your code can’t be made and your program crashes.
