Convert grpc::string_ref to std::string?

Question

How can I convert grpc::string_ref to a std::string to be used in internal library call?

I am trying to pass const grpc::string_ref& to jwt::decode(const std::string&) call

Ans: It seems grpc::string_ref provides the iterator and string is saved as char* , So the iterator can be used to iterate over the string_ref and append and create a std::string

Answer 1

You can use std::string's iterator constructor (6).

jwt::decode(std::string(ref.begin(), ref.end()))
