root?() public

Predicate method for root directories. Returns true if the pathname consists of consecutive slashes.

It doesn’t access the filesystem. So it may return false for some pathnames which points to roots such as /usr/...

# File ext/pathname/lib/pathname.rb, line 210
  def root?
    !!(chop_basename(@path) == nil && /#{SEPARATOR_PAT}/ =~ @path)
  end
