I could not find a fulfilling discussion comparing these three. Rust vs C++ are usually measured for kernel, embedded, performance-critical tasks, and such. Go vs Rust are often measured for server-side efficiency.
How would you evaluate Rust, Go, and C++ for implementing the "business logic" of an application that's going to run on a user's Linux/macOS/Windows personal computer, when the GUI mechanics are offloaded to the web widget?
