hololink::emulation::BaseTransmitter

Abstract base class for all transmitters.

Concrete transmitters (COETransmitter, RoCEv2Transmitter, UDPTransmitter) receive a DataPlaneCtxt* and downcast to their transport-specific ctxt (COECtxt, RoCEv2Ctxt, UDPCtxt) — those structs embed the platform DataPlaneCtxt extension as their first member, so the pointer cast is sound.

hololink::emulation::BaseTransmitter::BaseTransmitter() = default

Construct a new BaseTransmitter object.

Destructor

    const uint8_t *buffer,
    size_t buffer_size,
    FrameMetadata *frame_metadata = nullptr
)

Send a host buffer to the destination.

Returns: Bytes sent, or < 0 on error.
