tuple_object:next()

tuple_object

An analogue of the Lua next() function, but for a tuple object. When called without arguments, tuple:next() returns the first field from a tuple. Otherwise, it returns the field next to the indicated position.

However tuple:next() is not really efficient, and it is better to use tuple:pairs()/ipairs().

Returns

field number and field value

Return type

number and field type
