Struct PDUHeader

    pub version: U3,
    pub pdu_type: PDUType,
    pub direction: Direction,
    pub transmission_mode: TransmissionMode,
    pub crc_flag: CRCFlag,

}

The standard header attached to all CFDP PDUs.

Fields

version: U3

header version number.

pdu_type: PDUType

The type of the underlying payload.

direction: Direction

The direction in which this PDU is heading.

transmission_mode: TransmissionMode

The mode of the transaction.

crc_flag: CRCFlag

Whether a CRC is appended to the PDU byte stream.

large_file_flag: FileSizeFlag

Flag to indicate if the file size is less than the maximum u32 value.

pdu_data_field_length: u16

The length of attached payload.

When the CRC flag is set to CRCFlag::Present this struct will automatically account for the additional length during encoding.

segmentation_control: SegmentationControl

Flag to indicate if segmentation control is enabled for this transaction.

segment_metadata_flag: SegmentedData

Flag to indicate if metadata segmentation is enabled for this transaction.

source_entity_id: EntityID

Source entity identification number.

transaction_sequence_number: TransactionSeqNum

The sequence number of the transaction.

destination_entity_id: EntityID

Destination entity identification number.

Trait Implementations

impl Clone for PDUHeader

fn clone(&self) -> PDUHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PDUHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PDUEncode for PDUHeader

type PDUType = PDUHeader

fn encoded_len(&self) -> u16

Gets the encoded length must fit in a u16 for PDUs

fn encode(self) -> Vec<u8>

Encodes the PDU to a byte stream

fn decode<T: Read>(buffer: &mut T) -> PDUResult<Self::PDUType>

Attempts to decode a PDU from a byte stream

impl PartialEq for PDUHeader

fn eq(&self, other: &PDUHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
