  # You can control the layout of record fields. The only rules that can't be configured

  #     # - "indent N" -- insert a new line and N spaces from the beginning of the next line.
  #     equals: "indent 2"
  #
  #     # How to format first field of each record constructor.
  #     # Possible values:
  #     # - "same_line" -- "{" and first field goes on the same line as the data constructor.
  #     # - "indent N" -- insert a new line and N spaces from the beginning of the data constructor

  #     # Possible values:
