Struct PapPacket 

pub struct PapPacket {
    pub connection_id: u8,
    pub function: PapFunction,
    pub sequence_num: u16,
    pub data: Vec<u8>,
}

PAP packet structure

PAP packets are sent over ATP and have the following format:

• Byte 0: Connection ID
• Byte 1: Function code
• Bytes 2-3: Sequence number (for some functions)
• Remaining bytes: Function-specific data

Fields

connection_id: u8

function: PapFunction

sequence_num: u16

data: Vec<u8>

Implementations

impl PapPacket

pub const MIN_HEADER_LEN: usize = 2

Minimum header length (connection_id + function)

pub fn parse(buf: &[u8]) -> Result<Self, PapError>

Parse a PAP packet from bytes

pub fn to_bytes(&self, buf: &mut [u8]) -> Result<usize, PapError>

Encode a PAP packet to bytes

pub fn len(&self) -> usize

Get the total length of this packet when encoded

pub fn is_empty(&self) -> bool

Check if the packet is empty (no data)

pub fn to_atp_parts(&self) -> ([u8; 4], &[u8])

Convert to ATP user bytes and data payload

PAP transmits its header in the ATP user bytes.

• Byte 0: Connection ID
• Byte 1: Function code
• Bytes 2-3: Sequence number (or unused/zero)

pub fn parse_from_atp( user_bytes: [u8; 4], data: &[u8], ) -> Result<Self, PapError>

Parse from ATP user bytes and data payload

Trait Implementations

impl Clone for PapPacket

fn clone(&self) -> PapPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PapPacket

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

Formats the value using the given formatter.

impl PartialEq for PapPacket

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