Struct any 

Source 
pub struct any;
Expand description

Stands for a value of any type.

This is a documentation convention, not a real Lua type: where a signature says any, the function accepts (or may return) a value of any of the basic types — nil, boolean, number, string, table, function, userdata or thread.

Use type to find out at run time which type a value actually has:

print(type("hi"), type(42), type({}))    --> string   number   table
