abstract struct Value

• Value
• Object

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.
