abstract struct Value
Overview
Value
is the base type of the primitive types (Nil
, Bool
, Char
, Number
),
Symbol
, Pointer
, Tuple
, StaticArray
and all structs.
A Value
is passed by value: when you pass it to methods,
return it from methods or assign it to variables, a copy
of the value is actually passed.
This is not important for nil, bools, integers, floats, symbols,
pointers and tuples, because they are immutable, but with a mutable
Struct
or with a StaticArray
you have to be careful. Read their
documentation to learn more about this.
