Tuple
A tuple is a data structure where values are ordered and unchangeable. In Lua, tuples are implemented as tables.
Nothing more to discuss here. In one phrase: in Lua language tuple is just a table and nothing extra needs to be implemented.
Consider:
local tuple = {
42,
true,
"some value",
{ a = 2, b = 3 },
nil,
function()
print("something")
end,
}
-- Iterate
for i = 1, #tuple do
print(i, tuple[i])
end
--Output:
-- 1 42
-- 2 true
-- 3 some value
-- 4 table: 0x563597b49950
-- 5 nil
-- 6 function: 0x563597b45ba0
