wrote_chunk

Emitted immediately after writing a body chunk for a message.

Note that this signal is not parallel to [signal@ServerMessage:SoupServerMessage:got-chunk]; it is emitted only when a complete chunk (added with [method@MessageBody.append] or [method@MessageBody.append_bytes] has been written. To get more useful continuous progress information, use [signal@ServerMessage:SoupServerMessage:wrote-body-data].
