Overview

StrictStruct provides a struct by which accessing undefined fields raises a MethodMissing error. This protects against accessing fields that are not present in API Responses.

If you need to check whether a field exists in an api response, you can via name? methods.

struct = StrictStruct.new({ “foo” => 1, “bar” => [{ “baz” => 2 }, 3] })

struct.foo? # => true struct.brr? # => false struct.foo # => 1 struct.bar # => [StrictStruct<{ “baz” => 2 }>, 3] struct.brr # => NoMethodError struct # => 1 struct # => nil struct[:bar, 0, :baz] # => 2 struct[:bar, 0, :brr] # => nil
