Rust started as a project by the Mozilla Foundation, the people who support the Mozilla Firefox web browser. Rust does include concepts from a number of other languages to round out its features and how it solves common programming problems. In real world terms, Rust is designed to compete with or replace C and C++ as low level languages used in computer operating systems and other applications. However, digging deeper online reveals it is simply one of many reasons for the name. Wikipedia says the language is named after an amazing fungus called Rust. There is no official reason for the name Rust beyond a name that can be interpreted many different ways. Now that Rust is stable, anything published after May 2015 is likely accurate.įinally, the name of the language turns out to have an amusing back story. If you search online for tutorials and documentation, for example, you might find a few with inaccurate information. The best documentation and tutorials are on the Rust main website. The language also is open source, like other Mozilla projects, and has a strong active community around the language. However, Rust reportedly runs as quickly as low level languages C and C++. As a result, the language can be embedded in other languages and used for writing low level code like software drivers and operating systems. Instead, the Rust compiler tracks memory location and usage based on ownership and object lifetimes. Typically, programming languages have used garbage collection to track use of your computer memory and delete memory no longer needed. A new programming language is free to solve this problem while an existing language has past code and concepts to deal with. Which makes sense, if you think about it. Ownership enforces strict rules about how code is written to make it easier to manage the storage and indexing of your code in your computer memory. Connections within your code can’t be made and your program crashes. With some languages like C and C++, it is possible for the programming language to become confused about where your code resides in memory. The index makes it easy to find, process (compile), and run your code. When you write code, the programming language assigns your code to specific parts of your computer memory and indexes its location. The idea of ownership is fairly simple to explain. Python, Java, PHP, and other languages are higher level languages. 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. 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. Ownership helps solve critical security and runtime problems with memory management C and C++ programmers have dealt with for decades. To solve key programming-related problems in low level C and C++ languages, ownership is the primary concern of Rust. Rust 1.0, the first stable version of the language, was released on May 15, 2015. Yet Rust solves many key weaknesses of C, C++, and other languages. 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. In some ways, Rust is an upside down systems programming language. The new Rust programming language is designed to solve problems with operating systems and fix issues with C and other languages.
