std::span support?

[jcelerier]

Hello,

when I try to set a C++ callback of the form: std::function<void(std::span<uint8_t>) from python,
I get a std::bad_cast while invoking the callback from C++. Everything works fine when I use std::vector<uint8_t> instead.

Are there plans for std::span support ?

Thanks!

std::span is a C++20 feature. Features beyond c++17 are currently considered out of scope.
