Source

# File lib/prism/serialize.rb, line 28
def self.load(input, serialized)
  input = input.dup
  source = Source.for(input)

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

  input.force_encoding(loader.encoding)

  # This is an extremely niche use-case where the file was marked as binary
  # but it contained UTF-8-encoded characters. In that case we will actually
  # put it back to UTF-8 to give the location APIs the best chance of being
  # correct.
  if !input.ascii_only? && input.encoding == Encoding::BINARY
    input.force_encoding(Encoding::UTF_8)
    input.force_encoding(Encoding::BINARY) unless input.valid_encoding?
  end

  result
end

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