Expand description

Encode a 58-byte voice header.

Layout per ircDDBGateway/Common/HeaderData.cpp:637-684 (getDPlusData):

  • [0] 0x3A (length byte)
  • [1] 0x80 (type byte)
  • [2..6] “DSVT”
  • [6] 0x10 (header type)
  • [7..10] 0x00 0x00 0x00 (reserved)
  • [10] 0x20 (config)
  • [11..14] 0x00 0x01 0x02 (band1/2/3)
  • [14..16] stream_id little-endian
  • [16] 0x80 (header indicator)
  • [17..58] DStarHeader::encode_for_dsvt() (flag bytes zeroed, 41 bytes)

§Errors

Returns EncodeError::BufferTooSmall if out.len() < 58.
