Module gvsp 

GVSP packet parsing, reassembly and resend orchestration.

The GigE Vision Streaming Protocol delivers image data over UDP. Packets can arrive out of order or be dropped entirely; this module reconstructs complete frames while coordinating resend requests over GVCP. The implementation keeps copies to a minimum by writing directly into pooled [BytesMut] buffers that are subsequently frozen into [Bytes] once a frame is ready.

Structs

ChunkRaw

Raw GVSP chunk extracted from a payload or trailer block.

CompletedFrame

Representation of a fully reassembled frame ready for consumption.

FrameAssembly

Representation of a partially received frame.

FrameQueue

Frame queue used for communicating between the receiver task and the application.

PacketBitmap

Bitmap tracking received packets within a block.

Reassembler

Zero-copy block assembly state machine.

ResendPlanner

Helper struct tracking resend attempts for a given block.

StreamConfig

Stream configuration shared between the control plane and GVSP receiver.

Enums

GvspError

Errors raised while handling GVSP packets.

GvspPacket

Representation of a GVSP packet.

StreamDest

Destination for GVSP packets received by the stream.

Functions

coalesce_missing

Coalesce missing packet ranges into resend requests.

parse_chunks

Parse a chunk payload following the [id][reserved][length][data...] layout.

parse_packet

Parse a raw UDP payload into a GVSP packet.
