implementing std::function and lambda capturing in C++20 - advanced patterns with partial specialization
I'm having trouble with I've searched everywhere and can't find a clear answer... I'm stuck on something that should probably be simple..... After trying multiple solutions online, I still can't figure this out. I'm experiencing unexpected behavior with `std::function` and lambda expressions in C++20 when trying to partially specialize a template function. The goal is to use a lambda that captures variables by reference in a callback, but instead, I am working with a compilation behavior that says: `behavior: no suitable constructor exists to convert the provided expression to type`. Here's a simplified version of my code: ```cpp #include <iostream> #include <functional> template <typename T> void process(std::function<void()> func) { func(); } int main() { int x = 10; auto myLambda = [&](){ std::cout << "Value of x: " << x << std::endl; }; process<int>(myLambda); return 0; } ``` I expected this to print the value of `x`, but instead, I get the aforementioned compilation behavior. I've tried various ways to declare the lambda and different types for the `process` function, but nothing seems to work. Should I be using a different approach to pass the lambda, or is there a specific requirement for capturing variables in this context that I might be missing? I would appreciate any insights or workarounds for this scenario, especially if there's a specific C++20 feature that affects lambda behavior with `std::function`. My development environment is Windows. Am I missing something obvious? Has anyone else encountered this? I'm coming from a different tech stack and learning C++. Am I missing something obvious? I'd be grateful for any help. What's the correct way to implement this?
