}

NetworkPacketEvent records the details of a single packet sent or received on the network (in Linux kernel terminology, one sk_buff struct).

Fields

direction: Option<i32>

The direction traffic is flowing for this event.

interface: Option<String>

The name of the interface if available (e.g. ‘rmnet0’).

length: Option<u32>

The length of the packet in bytes (wire_size - L2_header_size). Ignored when using NetworkPacketEvent as the ctx in either NetworkPacketBundle or NetworkPacketContext.

uid: Option<u32>

The Linux user id associated with the packet’s socket.

tag: Option<u32>

The Android network tag associated with the packet’s socket.

ip_proto: Option<u32>

The packet’s IP protocol (TCP=6, UDP=17, etc).

tcp_flags: Option<u32>

The packet’s TCP flags as a bitmask (FIN=0x1, SYN=0x2, RST=0x4, etc).

local_port: Option<u32>

The local udp/tcp port of the packet.

remote_port: Option<u32>

The remote udp/tcp port of the packet.

icmp_type: Option<u32>

The 1-byte ICMP type identifier.

icmp_code: Option<u32>

The 1-byte ICMP code identifier.

Implementations

impl NetworkPacketEvent

pub fn direction(&self) -> TrafficDirection

pub fn interface(&self) -> &str

Returns the value of interface, or the default value if interface is unset.

pub fn length(&self) -> u32

Returns the value of length, or the default value if length is unset.

pub fn uid(&self) -> u32

Returns the value of uid, or the default value if uid is unset.

pub fn tag(&self) -> u32

Returns the value of tag, or the default value if tag is unset.

pub fn ip_proto(&self) -> u32

Returns the value of ip_proto, or the default value if ip_proto is unset.

pub fn tcp_flags(&self) -> u32

Returns the value of tcp_flags, or the default value if tcp_flags is unset.

pub fn local_port(&self) -> u32

Returns the value of local_port, or the default value if local_port is unset.

pub fn remote_port(&self) -> u32

Returns the value of remote_port, or the default value if remote_port is unset.

pub fn icmp_type(&self) -> u32

Returns the value of icmp_type, or the default value if icmp_type is unset.

pub fn icmp_code(&self) -> u32

Returns the value of icmp_code, or the default value if icmp_code is unset.

Trait Implementations

impl Clone for NetworkPacketEvent

fn clone(&self) -> NetworkPacketEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NetworkPacketEvent

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

Formats the value using the given formatter.

impl Default for NetworkPacketEvent

fn default() -> Self

Returns the “default value” for a type.

impl Message for NetworkPacketEvent

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

impl PartialEq for NetworkPacketEvent

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