Is there a way for me to get the total number of elements in a mapping in Solidity?

  • Not unless you count it by yourself (increment after the creation of a new entry, decrement after the deletion of an existing entry). – sea212 Apr 5 at 22:43

You can't. There is no way to know how many entries there are in a mapping.

If you need to keep tract of the mapping's elements you can use a separate array which holds extra information about the mapping elements
