Struct Packet 

pub struct Packet<'a> { /* private fields */ }

Implementations

impl<'a> Packet<'a>

pub fn from_bytes( buf: &'a [u8], link_type: LinkType, mode: ParseMode, ) -> Result<Self, PacketHeaderError>

Parse a packet from raw bytes using the specified link type and parse mode.

This method directly parses all protocol layers without using an iterator, collecting them into a structured Packet.

Arguments

• buf - The raw packet bytes
• link_type - The link layer type of the packet
• mode - Parse mode: Outermost ignores tunnels, Innermost parses through them

pub fn link(&self) -> &LinkLayer<'a>

Returns a reference to the link layer header.

pub fn arp(&self) -> Option<&ArpHeaderFull<'a>>

Returns a reference to the ARP header, if present.

pub fn network(&self) -> Option<&NetworkLayer<'a>>

Returns a reference to the network layer header, if present.

pub fn transport(&self) -> Option<&TransportLayer<'a>>

Returns a reference to the transport layer header, if present.

pub fn tunnels(&self) -> &[NetworkTunnelLayer<'a>]

Returns a slice of IP tunnel layer headers.

pub fn data(&self) -> &'a [u8]

Returns the remaining payload data after all parsed headers.

Trait Implementations

impl<'a> Clone for Packet<'a>

fn clone(&self) -> Packet<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Packet<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Packet<'a>

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

Formats the value using the given formatter.

impl TryFrom<&Packet<'_>> for SmallVec<[VniLayer; 4]>

Convert a Packet to a VNI layer stack

This efficiently extracts VNI information from:

1. Link layer (VLAN tags) - produces SmallVec<[VniLayer; 2]>
2. Tunnel layers - each NetworkTunnelLayer converted to VniLayer

The result is the concatenation of link VNI layers followed by tunnel VNI layers. This operation may fail (returning Err(())) if any tunnel layer cannot be converted.

type Error = ()

The type returned in the event of a conversion error.

fn try_from(packet: &Packet<'_>) -> Result<Self, Self::Error>

Performs the conversion.
