Smarter way to strip trailing “\r\n” in UART debug output?

When using the standard lambda for UART debug, the output string in the log includes the delimiter.

Example log output:

15:57:30 [D] [uart_debug:158] <<< “1-0:71.7.0(000.8*A)\r\n”.

Question: Is there a cleaner or smarter way to strip the trailing \r\n than the rather bloated solution 2 below?

  1. Standard UARTDebug that includes the delimiter:
   uart:
    . . .
    debug:
      direction: RX
      dummy_receiver: false
      after:
        delimiter: "\r\n"
        timeout: 500ms
      sequence:
        - lambda: UARTDebug::log_string(direction, bytes);
  1. Bloated lambda to strip trailing “\r\n”:
   uart:
     . . .
     debug:
       direction: RX
       dummy_receiver: false
       after:
         delimiter: "\r\n"
         timeout: 500ms
       sequence:
         lambda: |-
           auto it = std::find(bytes.begin(), bytes.end(), '\r');
           size_t pos = (it != bytes.end()) ? std::distance(bytes.begin(), it) : bytes.size();
           std::vector<uint8_t> out(bytes.begin(), bytes.begin() + pos);
           UARTDebug::log_string(direction, out);
