A generic response packet that can be either an OK packet, an EOF packet, or an ERR packet.

A generic response packet that can be either an OK packet, an EOF packet, or an ERR packet.

For most commands the client sends to the server, the server returns one of these packets in response:

  • An OKPacket indicates that the command was successful.
  • An EOFPacket indicates that the command was successful, but that the server has no more data to send in response to the command.
  • An ERRPacket indicates that the command was unsuccessful.
