Represents a packet with its different headers and associated lengths.

Fields

status: u64

Per packet status bits.

packet_raw_len: u32

On wire full packet length (from the per-packet PCAP header).

packet_l2_len: u32

On wire packet length starting from layer2.

packet_len: u32

Packet length depending on Tranalyzer2 PACKETLENGTH value, see networkHeaders.h for details.

snap_len: u32

Packet snapped length

snap_l2_len: u32

Packet snapped length starting from layer 2.

snap_l3_len: u32

Packet snapped length starting from layer 3.

snap_l4_len: u16

Packet snapped length starting from layer 4.

snap_l7_len: u16

Packet snapped length starting from layer 7.

packet_l7_len: u16

Packet payload length: layer 7 length.

l2_hdr_len: u16

Length of the layer 2 header (Ethernet, …).

l3_hdr_len: u16

Length of the layer 3 header (IPv4, IPv6, …).

l4_hdr_len: u16

Length of the layer 4 header (TCP, UDP, ICMP, …).

inner_vlan: u16

Inner VLAN ID

src_port: u16

Source port in host order.

dst_port: u16

Destination port in host order.

l2_type: u16

Type of the layer 2 header.

outer_l2_type: u16

Outer type of the layer 2 header.

Implementations

impl Packet

pub fn timestamp(&self) -> f64

Timestamp of when the packet was captured (as the number of seconds since 1970-01-01).

pub fn ethernethdr(&self) -> Option<&EthernetHeader>

Returns an EthernetHeader if the packet contains an Ethernet header and is long enough. Returns None otherwise.

pub fn ip4hdr(&self) -> Option<&Ip4Header>

Returns an Ip4Header if the packet contains an IPv4 header and is long enough. Returns None otherwise.

pub fn ip6hdr(&self) -> Option<&Ip6Header>

Returns an Ip4Header if the packet contains an IPv6 header and is long enough. Returns None otherwise.

pub fn tcphdr(&self) -> Option<&TcpHeader>

Returns a TcpHeader if the packet contains a TCP header and is long enough. Returns None otherwise.

pub fn udphdr(&self) -> Option<&UdpHeader>

Returns a UdpHeader if the packet contains a UDP header and is long enough. Returns None otherwise.

pub fn icmphdr(&self) -> Option<&IcmpHeader>

Returns an IcmpHeader if the packet contains an ICMP header and is long enough. Returns None otherwise.

pub fn l7_header(&self) -> &[u8]

Returns the layer 7 as a slice of bytes.

This is how the layer 7 is typically accessed in content processing plugins.

pub fn raw_l2_header(&self) -> &[u8]

Returns the layer 2 header as a slice of bytes.

pub fn raw_l3_header(&self) -> &[u8]

Returns the layer 3 header as a slice of bytes.

This function can be used to access the IP options as a Rust inferface is not yet implemented for IPv4 options and IPv6 extension headers.

pub fn raw_l4_header(&self) -> &[u8]

Returns the layer 4 header as a slice of bytes.

This function can be used to access TCP options as a Rust interface is not yet implemented.

pub fn l3_type(&self) -> L3Type

Type of the layer 3 header as defined in L3Type.

pub fn l4_type(&self) -> L4Type

Type of the layer 4 header as defined in L4Type.
