5/// - `'i'`: Integers, passed as `collect_values[].v_int`
6///  - `'l'`: Longs, passed as `collect_values[].v_long`
7///  - `'d'`: Doubles, passed as `collect_values[].v_double`
8///  - `'p'`: Pointers, passed as `collect_values[].v_pointer`
9///
10///  It should be noted that for variable argument list construction,
11///  ANSI C promotes every type smaller than an integer to an int, and
12///  floats to doubles. So for collection of short int or char, `'i'`
13///  needs to be used, and for collection of floats `'d'`.
14/// The [`TypeValueTable`][crate::TypeValueTable] provides the functions required by the [`Value`][crate::Value]
15/// implementation, to serve as a container for values of a type.
