-- A GHashTableIter structure represents an iterator that can be used
-- to iterate over the elements of a t'GI.GLib.Structs.HashTable.HashTable'. GHashTableIter
-- structures are typically allocated on the stack and then initialized
-- with 'GI.GLib.Structs.HashTableIter.hashTableIterInit'.
-- 
-- The iteration order of a t'GI.GLib.Structs.HashTableIter.HashTableIter' over the keys\/values in a hash
-- table is not defined.
