Example: Working with Different String APIs

​An interesting use case for string_view is when you use it in code that works with different string implementations.

For example, you might have CString from MFC, const char* from C-APIs, QString from QT, and of course std::string.

Rather than creating overloads for different string types, you might leverage string_view!

For example:

void Process(std::string_view sv) { }

If you want to use Process with different string implementations, then all you have to do is to create a string view from your type. Most of the string types should easily allow that.

For example:
