+module Gem::URI
+
+  #
+  # The "file" Gem::URI is defined by RFC8089.
+  #
+  class File < Generic
+    # A Default port of nil for Gem::URI::File.
+    DEFAULT_PORT = nil
+
+    #
+    # An Array of the available components for Gem::URI::File.
+    #
+    COMPONENT = [
+      :scheme,
+      :host,
+      :path
+    ].freeze
+
+    #
+    # == Description
+    #
+    # Creates a new Gem::URI::File object from components, with syntax checking.
+    #
+    # The components accepted are +host+ and +path+.
+    #
+    # The components should be provided either as an Array, or as a Hash
+    # with keys formed by preceding the component names with a colon.
+    #
+    # If an Array is used, the components must be passed in the
+    # order <code>[host, path]</code>.
+    #
+    # A path from e.g. the File class should be escaped before
+    # being passed.
+    #
+    # Examples:
+    #
+    #     require 'rubygems/vendor/uri/lib/uri'
+    #
+    #     uri1 = Gem::URI::File.build(['host.example.com', '/path/file.zip'])
+    #     uri1.to_s  # => "file://host.example.com/path/file.zip"
+    #
+    #     uri2 = Gem::URI::File.build({:host => 'host.example.com',
+    #       :path => '/ruby/src'})
+    #     uri2.to_s  # => "file://host.example.com/ruby/src"
+    #
+    #     uri3 = Gem::URI::File.build({:path => Gem::URI::escape('/path/my file.txt')})
+    #     uri3.to_s  # => "file:///path/my%20file.txt"
