Here ``_KeyType`` can be almost any type except for a mapping, a dynamically sized array, a contract, an enum and a struct. ``_ValueType`` can actually be any type, including mappings. -Mappings can be seen as hashtables which are virtually initialized such that +Mappings can be seen as `hash tables <https://en.wikipedia.org/wiki/Hash_table>`_ which are virtually initialized such that every possible key exists and is mapped to a value whose byte-representation is all zeros: a type's :ref:`default value <default-value>`. The similarity ends here, though: The key data is not actually stored in a mapping, only its ``keccak256`` hash used to look up the value. |
