Struct TelemetryPacketHeader

pub struct TelemetryPacketHeader {
    pub sync: u16,
    pub packet_type: TelemetryPacketType,
    pub timestamp: u32,
    pub counter: u16,
    pub length: u16,
    pub checksum: u16,
}

This gets attached to each telemetry packet “in front” of it, conveying meta information

Fields

sync: u16

A constant identifying the start of a packet

packet_type: TelemetryPacketType

A unique identifier describing the following packet’s content

timestamp: u32

The timestap from the gcu (flight computer) (NOT GPS!) when this packet header has been created

counter: u16

Counting packets send out by the gcu (flight computer), rolling over every u16::MAX

length: u16

The length in bytes of the following packet

checksum: u16

A checksum to verify the integrity of the following packet FIXME - currently the algorithm used is unknown

Implementations

impl TelemetryPacketHeader

pub fn new() -> Self

pub fn forge(packet_type: TelemetryPacketType) -> Self

A re-implementation of make_packet_stub

pub fn get_gcutime(&self) -> f64

Blatent copy of bfsw’s timestamp_to_double

Trait Implementations

impl Clone for TelemetryPacketHeader

fn clone(&self) -> TelemetryPacketHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TelemetryPacketHeader

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

Formats the value using the given formatter.

impl Display for TelemetryPacketHeader

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

Formats the value using the given formatter.

impl PartialEq for TelemetryPacketHeader

fn eq(&self, other: &TelemetryPacketHeader) -> 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.

impl Serialization for TelemetryPacketHeader

const HEAD: u16 = 37_099u16

Byte marker to mark beginning of payload

const TAIL: u16 = 0u16

Byte marker to mark end of payload

const SIZE: usize = 13usize

The SIZE is the size of the serialized bytestream INCLUDING 4 bytes for head and tail bytes. In case the struct does NOT HAVE a fixed size, SIZE will be 0 (so default value of the trait

fn from_bytestream( stream: &Vec<u8>, pos: &mut usize, ) -> Result<Self, SerializationError>

Decode a serializable from a bytestream

fn to_bytestream(&self) -> Vec<u8>

Encode a serializable to a bytestream

fn verify_fixed( stream: &Vec<u8>, pos: &mut usize, ) -> Result<(), SerializationError>

Verify that the serialized representation of the struct has the correct size, including header + footer.

fn from_bytestream_alt( bytestream: &Vec<u8>, pos: &mut usize, ) -> Result<Self, SerializationError>

where Self: Sized,

Decode a serializable from a bytestream. This provides an alternative method to get the packet. If not implemented, it will be the same as from_bytestream.
