Rust programming language designed by code#
However, to get the beat performance out of a computer, the code had to be concurrent. But by 2005, microprocessor manufacturers had developed techniques that exploited some of the speed advantage of multi-core CPUs, even if the code was not specifically written to be concurrent. In the 1990s, only supercomputers were multi-processor, and programming them using concurrency was considered a black art. When CPU speeds hit the wall, computer manufacturers lost no time in coming up with a new approach to making computers run at faster speeds. The fastest CPU ever produced in a lab was the AMD Bulldozer, which reached 8.4 GHz and had to be cooled using liquid nitrogen. In addition, there were two other factors-gate delay and the speed of electric transmission-although the heat alone was enough of a problem to prevent CPU clock speeds from going beyond 3.7 Mhz. As CPUs got bigger (more logic gates) and faster (more clock cycles), they reached the point where it was no longer possible to get rid of the heat using conventional, affordable technology (fans and heat sinks).
Computer manufacturers were facing a physics problem: For every “clock cycle” of a central processing unit (CPU), a few hundred million “logic gates” were generating heat as they were either charged or their charge was released. The deficiencies Rust wanted to solve ConcurrencyĪ hardware limitation had started to materialize shortly before the creation of Rust. We looked at its history and turned to Steve Klabnik and Ashley Williams, two current members of the Rust core team, to discover the answers to these questions. So what deficiencies inspired Graydon Hoare, then a programmer at the nonprofit Mozilla, to start working in 2006 on a new language he called Rust? And how was Rust built to handle those deficiencies? It’s true that every generation of programmers is inevitably seduced by the lure of new languages, and why not? Novelty and variety are the spice of life, and so far, the Online Historical Encyclopaedia of Programming Languages has identified 8,945 languages.īut what motivates language designers to create a new language in the first place? Usually it’s a desire to fix something that is broken, to remedy some deficiency in the languages already in existence, or to provide a different approach to writing code. Moreover, it is one of the fastest-growing languages. In 2019, Stack Overflow reported that the Rust programming language was the “most loved” language for the third year in a row.
