Rocket vs Xamarin: What are the differences?
Rocket: Web Framework for Rust. Rocket is a web framework for Rust that makes it simple to write fast web applications without sacrificing flexibility or type safety. All with minimal code; Xamarin: Create iOS, Android and Mac apps in C#. Xamarin’s Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual Studio*), as well as skills in .NET and the C# programming language, to create mobile applications for the industry’s most widely-used mobile devices, including Android-based smartphones and tablets, iPhone, iPad and iPod Touch.
Rocket and Xamarin are primarily classified as "Frameworks (Full Stack)" and "Cross-Platform Mobile Development" tools respectively.
"Uses all the rust features extensively" is the primary reason why developers consider Rocket over the competitors, whereas "Power of c# on mobile devices" was stated as the key factor in picking Xamarin.
