Struct AdspPacket 

pub struct AdspPacket {
    pub descriptor: AdspDescriptor,
    pub connection_id: u16,
    pub first_byte_seq: u32,
    pub next_recv_seq: u32,
    pub recv_window: u16,
    pub flags: u8,
}

ADSP packet header structure

ADSP (AppleTalk Data Stream Protocol) provides connection-oriented, full-duplex byte-stream communication over DDP.

Packet format:

• Byte 0: Descriptor (packet type)
• Bytes 1-2: Connection ID (u16, big-endian)
• Bytes 3-6: First Byte Sequence number (u32, big-endian)
• Bytes 7-10: Next Receive Sequence number (u32, big-endian)
• Bytes 11-12: Receive Window size (u16, big-endian)
• Remaining bytes: Data payload (not owned by this struct)

Fields

descriptor: AdspDescriptor

Packet type/descriptor

connection_id: u16

Connection identifier

first_byte_seq: u32

Sequence number of the first data byte in this packet

next_recv_seq: u32

Next expected receive sequence number

recv_window: u16

Receive window size (flow control)

flags: u8

Flags (Control, Ack, EOM, Attention)

Implementations

impl AdspPacket

pub const HEADER_LEN: usize = 13

ADSP header length in bytes

pub const FLAG_CONTROL: u8 = 0x80

pub const FLAG_ACK: u8 = 0x40

pub const FLAG_EOM: u8 = 0x20

pub const FLAG_ATTENTION: u8 = 0x10

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

Parse an ADSP header from bytes

Returns the parsed header. The caller is responsible for handling any data following the header in the buffer.

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

Encode the ADSP header to bytes

Returns the number of bytes written (always HEADER_LEN). The caller is responsible for appending any data payload.

Trait Implementations

impl Clone for AdspPacket

fn clone(&self) -> AdspPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdspPacket

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

Formats the value using the given formatter.

impl PartialEq for AdspPacket

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