The video tutorial explores the use of std::string_view as a function parameter, highlighting its benefits for observing strings without taking ownership. It explains the scenarios where std::string_view is preferable over std::string, especially in terms of performance when dealing with long strings. The tutorial also covers the implications of using std::string_view in terms of safety and efficiency, and provides a performance comparison between std::string and std::string_view. The conclusion emphasizes the importance of using std::string_view for observing strings to enhance performance and express intent clearly.

What should be documented when a string view is retained beyond the function call?

Describe the potential issues that arise when storing an SCD string view inside a struct.

How does the compiler optimize the use of CD string views with short string literals?
