vector of strings and array_view of string_views conversion conundrum

[positron96]

This is probably a generic C++ question, but it deals with ETL's hierarchy of classes, so I hope it belongs here.

I want to have a function that accepts a container of string-like objects (vectors of any size of strings of any size and C arrays of C strings). I've created it like this: func(const etl::array_view<etl::string_view> &arg).

With this I can call it for fixed arrays like this:

etl::string_view items[] = { "str1", "str2" };
func(items);

Here a etl::array_view is created implicitly from a C-array.

Also I can call it for vectors like this:

etl::vector<etl::string<L>, N> strings;
/* populate vector here  */
etl::vector<etl::string_view, N> lines;
for(const auto &t: strings) lines.push_back(t);
func(lines);

So there is an owning vector strings of strings which is copied to a vector lines that only stores views of that strings. The function is called for lines. I cannot pass a vector<string> directly because it's not actually a subclass of vector<string_view> (that can be used to create an array_view<string_view>).
The question is this: is there a way for me to pass a vector<string> directly to my function without creating another vector<string_view>? Can I modify function declaration to accept a vector of strings as well as something created from C array of C strings?

You could possibly modify func to be a template function that takes a const reference to a container that implements begin() and end().

template <typename TContainer>
func(const TContainer& container)
{
  for (const auto& s : container)
  {
  //...
  }
}
