Description

Hi,

Due to the following line:
T *new_data = new T[count];
in the AsyncProgress(Queue)Worker class T (your progress class) is required to have a default constructor.

I have prepared a patch which makes use of C++17 (std::aligned_alloc and std::uninitialized_copy) features and removes the necessity of the progress struct having a default constructor.

Should I wrap the patch in a feature guard (__cplusplus macro check) and file a merge request?

Research direction

Start at the AsyncProgress(Queue)Worker allocation using new T[count]. Review the proposed C++17 allocation and construction approach, including compatibility with supported compilers. Done means progress types no longer require a default constructor without breaking existing users or supported language versions.
