The simplest thing to do is just use a vector. This is C++. Just use a vector. Not an array. Also, in C++, you should be using "struct" only at the definition of the struct. I see you're using "struct" all over. This looks like C code. Is this C code?

That is a function returning a pointer not an array. Its a perfectly legal declaration. I think you need to revise pointers and arrays and the similarities and differences. Any book on C or C++ will cover this. In particular you seem to be confusing functions which return a pointer, which...
We cover function templates in lesson 11.6 -- Function templates. Since std::array is defined like this: template<typename T, std::size_t N> // N is a non-type template parameter struct array; Copy We can create a function template that uses the same template parameter declaration: #in...

I'm looking for some guidance on the best way to return a large byte array to Python code and/or share access to raw memory between Rust and Python. Basically, my application transfers large amounts of data over the network in Rust and then hands the data over to Python (but in some...
