Overview

AnyOf is used for allowing multiple shapes to be matched a single value. If any of the shapes match the value, the value is considered a match. If none of the shapes match the value, the value is considered a mismatch. AnyOf is used in the following way: Katachi::Comparator.compare(value, Katachi::AnyOf[shape1, shape2, shape3])

def each(&) = @shapes.each(&)

#inspect ⇒ Object

normally this .inspect redefinition would be for .to_s but Hash.to_s calls inspect on the keys and values, so we have to redefine inspect instead if we want a user-friendly string representation of complex objects

def inspect = "AnyOf[#{@shapes.map(&:inspect).join(", ")}]"

#kt_compare(value) ⇒ Object

AnyOf is considered a match if any of the shapes match the value If none of the shapes match the value, AnyOf is considered a mismatch
