Member Data Documentation

std::vector<Label> Pothos::Packet::labels

Labels associated with the payload. Each label index is an element-offset relative to the start of the payload. The element size can be determined from the type of the payload buffer.

ObjectKwargs Pothos::Packet::metadata

Arbitrary metadata for this message. Use metadata to associate arbitrary information with the payload. The are no specific requirements about what goes into metadata. The metadata structure is a dictionary of key-value pairs, where the keys for this dictionary are exclusively strings, and the values are opaque Objects which can contain anything.

BufferChunk Pothos::Packet::payload

The buffer payload for this message. The payload is just a memory buffer and a length in bytes. Payload can contains a slice of a continuous byte stream, a UDP datagram, a packet in a MAC layer protocol, etc... The interpretation of this payload buffer is up to the user.
