When sending a complete HTTP message at once and the semantics of the message are that the connection should be closed to indicate the end of the message.

partial_message

The incoming message is incomplete.

This happens when the end of stream is reached during parsing and some octets have been received, but not the entire message.

need_more

unexpected_body

This error is returned when attempting to parse body octets into a message container which has the empty_body body type.empty_body

need_buffer
