support for raw frames in PacketEncoder #691
Conversation
in my opinion the fields should be public because the structure is low level
| self.buf.put_bytes(0, data_prefix_len); | ||
| self.buf | ||
| .copy_within(start_len..start_len + data_len, start_len + data_prefix_len); | ||
| .copy_within(from..from + data_len, from + data_prefix_len); |

nit: I don't like the arbitrary var name changes. IMO this makes the code less readable, and the extra diff makes harder to review.

yep, maybe i was too lazy with this, this is looks like this bc i didnt interpreted the code chunk that compresses the packet

i think the new names for the vars make sense, because "start_len" was used for the length of the buffer before pushing the frame's bytes, but now it makes sense that its named "from", i changed the var name because i felt that "start_len" didnt maked that much sense for the argument's var name
| /// frames the bytes in a range from `from` to the end of the buffer, framing is: | ||
| /// adding a packet length varint to the start of the frame | ||
| /// adding a data length varint after the packet length, if compression is enabled | ||
| /// compressing the packet, if compression is enabled | ||
| pub fn enframe_from(&mut self, from: usize) -> anyhow::Result<()> { |

nit: "Framing" is not common terminology. It's either obfuscating a concept that can be described in more simple terms, or its adding just adding jargon to something that's already complex.
i want to be able to push raw stuff like |
Objective
its not possible to push a frame to the
PacketEncoderif its notPacket + Encode, this means that if i have a raw frame i can't push it because its not deserialized, so i cant usePacketEncoderto compress/encrypt my raw packetsSolution
i added
enframe_frommethod, which enframes a rightmost portion of the buffer which includes adding a packet length varint, a data length varint and compressing, this was already done internally by theappend_packetmethod but now its a method so we can re-use this logic, and of courseappend_frameandprepend_framemethods
