# module Nokogiri::CSS::XPathVisitor::BuiltinsConfig

Enum to direct `XPathVisitor` when to use `Nokogiri` builtin XPath functions.

### Constants

ALWAYS

  Always use `Nokogiri` builtin functions whenever possible. This is probably only useful for testing.

NEVER

  Never use `Nokogiri` builtin functions, always generate vanilla XPath 1.0 queries. This is the default when calling `Nokogiri::CSS.xpath_for` directly.

OPTIMAL

  Only use `Nokogiri` builtin functions when they will be faster than vanilla XPath. This is the behavior chosen when searching for `CSS` selectors on a `Nokogiri` document, fragment, or node.
