Struct CcsdsPacketCreatorWithReservedData 

pub struct CcsdsPacketCreatorWithReservedData<'buf> { /* private fields */ }

CCSDS packet creator with optional support for a CRC16 CCITT checksum appended to the end of the packet and support for copying into the user buffer directly.

This packet creator variant reserves memory based on the required user data length specified by the user and then provides mutable or shared access to that memory. This is useful to avoid an additional slice for the user data and allow copying data directly into the packet.

Please note that packet creation has to be completed using the Self::finish call.

Implementations

impl<'buf> CcsdsPacketCreatorWithReservedData<'buf>

pub const HEADER_LEN: usize = 6usize

CCSDS header length.

pub fn packet_len_for_user_data_with_checksum( user_data_len: usize, ) -> Option<usize>

Calculate the full CCSDS packet length for a given user data length and with a CRC16 checksum.

pub fn new( sp_header: SpacePacketHeader, packet_type: PacketType, packet_data_len: usize, buf: &'buf mut [u8], checksum: Option<ChecksumType>, ) -> Result<Self, CcsdsPacketCreationError>

Generic constructor.

pub fn new_with_checksum( sp_header: SpHeader, packet_type: PacketType, payload_len: usize, buf: &'buf mut [u8], ) -> Result<Self, CcsdsPacketCreationError>

Constructor which always appends a CRC16 checksum at the packet end.

pub fn new_tm_with_checksum( sp_header: SpHeader, payload_len: usize, buf: &'buf mut [u8], ) -> Result<Self, CcsdsPacketCreationError>

Constructor for telemetry packets which always appends a CRC16 checksum at the packet end.

pub fn new_tc_with_checksum( sp_header: SpHeader, payload_len: usize, buf: &'buf mut [u8], ) -> Result<Self, CcsdsPacketCreationError>

Constructor for telecommand packets which always appends a CRC16 checksum at the packet end.

impl CcsdsPacketCreatorWithReservedData<'_>

pub fn raw_buffer(&self) -> &[u8]

Raw full buffer this packet is constructed in.

pub fn packet_len(&self) -> usize

Full packet length.

pub fn sp_header(&self) -> &SpHeader

Space packet header.

pub fn ccsds_packet_id_and_psc(&self) -> CcsdsPacketIdAndPsc

CcsdsPacketIdAndPsc structure for this packet.

pub fn packet_data_mut(&mut self) -> &mut [u8]

Mutable access to the packet data field.

pub fn packet_data(&mut self) -> &[u8]

Read-only access to the packet data field.

pub fn finish(self) -> usize

Finish the packet generation process.

This packet writes the space packet header. It also calculates and appends the CRC checksum when configured to do so.
