Suppose that we have a contract field set up like such:: - - struct User { - mapping(string => string) comments; - } - - function somefunction public { - User user1; - user1.comments["Hello"] = "World"; - User user2 = user1; - } - -In this case, the mapping of the struct being copied over into ``user2`` is ignored as there is no "list of mapped keys". -Therefore it is not possible to find out which values should be copied over. - How do I initialize a contract with only a specific amount of wei? ================================================================== -- cgit v1.2.3
