Hello! Thank you so much! I actually later resolved that I may not necessarily need to reimplement something. But I do have some question about accessors in concurrent hash map. I'm trying to understand how regular accessor allows updates in the map but const_accessor does not. From online examples, I found out the standard way of using this map is through creating an appropriate accessor, and call the lookup with the key and accessor. I find out an insert will create an accessor, insert with the key and accessor, and assign accessor's second to the value we want to insert. So can I say accessors are set to copy the values of the key not the pointers to the values? Thanks.
