What is the best way to write etl string_view to cout?

[mike919192]

etl::string_view does not have an overload to write to cout. std::string_view does support this:

std::cout << view << '\n';

I made a test to provide my own overload and this is working.

std::ostream &operator<<(std::ostream &os, etl::string_view view)
{
    os.write(view.data(), view.size());
    return os;
}

This could be even more generalized if you want to avoid directly referencing std. This is also working, but maybe could cause some issues with overload resolution.

template <typename T>
T &operator<<(T &os, etl::string_view view)
{
    os.write(view.data(), view.size());
    return os;
}

Just curious if anyone has run into this before and any other solutions.
