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.

Instance Method Summary

Instance Method Detail

def ==(other : JSON::Any)Source

def ==(other : YAML::Any)Source

def ==(other)Source

Returns false.

def dupSource

Returns a shallow copy of this object.

Because Value is a value type, this method returns self, which already involves a shallow copy of this object because value types are passed by value.
