Struct ParsedPacket 

pub struct ParsedPacket {
    pub raw: Vec<u8>,
    pub ip_version: IpVersion,
    pub src_ip: String,
    pub dst_ip: String,
    pub ttl: u8,
    pub total_len: usize,
    pub ip_payload_offset: usize,
    pub transport: TransportProtocol,
}

A fully parsed IP packet with IP and transport layer information.

Fields

raw: Vec<u8>

Raw bytes of the original packet.

ip_version: IpVersion

IP version.

src_ip: String

Source IP address as string.

dst_ip: String

Destination IP address as string.

ttl: u8

TTL (IPv4) or hop limit (IPv6).

total_len: usize

Total packet length in bytes.

ip_payload_offset: usize

Byte offset where the IP payload starts (after IP header).

transport: TransportProtocol

Parsed transport layer.

Implementations

impl ParsedPacket

pub fn parse(raw: Vec<u8>) -> Result<Self, VCLError>

Parse a raw IP packet (IPv4 or IPv6) into a ParsedPacket.

Errors

Returns VCLError::InvalidPacket if:

• The packet is empty or too short
• The IP header is malformed

pub fn is_ipv4(&self) -> bool

Returns true if this packet is IPv4.

pub fn is_ipv6(&self) -> bool

Returns true if this packet is IPv6.

pub fn is_destined_for(&self, ip: &str) -> bool

Returns true if the destination IP matches ip.

pub fn is_from(&self, ip: &str) -> bool

Returns true if the source IP matches ip.

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

Returns the payload slice — bytes after the IP header.

pub fn is_dns(&self) -> bool

Returns true if this is a DNS query (UDP dst port 53).

pub fn is_ping(&self) -> bool

Returns true if this is an ICMP echo request (ping).

pub fn summary(&self) -> String

Returns a human-readable summary of this packet.

Trait Implementations

impl Clone for ParsedPacket

fn clone(&self) -> ParsedPacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParsedPacket

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

Formats the value using the given formatter.
