Rust Tutorial – eine Einführung in die Programmiersprache

In der Softwarebranche herrscht niemals Stillstand, und beinahe im Tagesrhythmus wird man mit neuen Technologien, Frameworks oder Programmiersprachen konfrontiert. Zuweilen kann das schon fast in einem Ohnmachtsgefühl resultieren, da es uns mittlerweile unmöglich geworden ist, überall und auf jedem Gebiet einigermaßen informiert, geschweige denn Spezialist zu sein. Die Herausforderung, der wir uns aktuell gegenübersehen, lautet zum einen, einen guten Überblick über Trends und Innovationen zu behalten, und zum anderen, sich von Zeit zu Zeit ein Thema herauszupicken und sich näher damit zu beschäftigen. In unserem Fall soll das die Programmiersprache Rust sein, der wir in diesem Tutorial unsere Zeit und Aufmerksamkeit schenken. Dabei gehen wir davon aus, dass bereits Erfahrungen aus ähnlichen Programmiersprachen wie C++, C#, Java oder JavaScript vorhanden sind.
