  input = input.dup
  source = Source.new(input)
  loader = Loader.new(source, serialized)
  result = loader.load_result

  input.force_encoding(loader.encoding)
  result
end

.load_tokens(source, serialized) ⇒ Object

Deserialize the tokens represented by the given string into a parse result.

# File 'lib/prism/serialize.rb', line 49
