Summary

None

Purpose of change

This avoids unnecessary reference passing.
There is no need to use const std::string_view &, because std::string_view itself is a reference to a string (std::string or const char*).

Describe the solution

Although const std::string_view is closer to the original semantics, since it is a function parameter, omitting the const modifier here might be more appropriate.

Although this change might have an impact on performance, even if it does, it would be negligible.
The main purpose is to simplify the code, so I filled in "None" in the Summary section.

Testing

This change will hardly affect the behavior of the code, so no testing is necessary.
