WebbAs others said, C# compiles to a IR and not to native code, i.e. it needs to be run on a virtual machine. Idea: make a C# application and call some sort of Rust entry function from C#, pass a delegate to Rust (not sure if it is possible tho), and then use this delegate to call C# code. By doing this you will be running Rust side by side with a ... Webb19 aug. 2024 · Rust is a low-level statically-typed multi-paradigm programming language that’s focused on safety and performance. Rust solves problems that C/C++ has been struggling with for a long time, such as memory errors and building concurrent programs. It has three main benefits: better memory safety due to the compiler;

Any Python-native object reference (such as &PyAny, &PyList, or &PyCell) can be used to call Python functions. PyO3 offers two APIs to make function calls: call - call any callable Python object. call_method - call a method on the Python object. Both of these APIs take args and kwargs arguments (for positional ...
