Struct pnet::packet::ipv4::Ipv4Packet

pub struct Ipv4Packet<'p> {
    // some fields omitted
}

A structure enabling manipulation of on the wire packets

Methods

impl<'a> Ipv4Packet<'a>

fn new<'p>(packet: &'p [u8]) -> Option<Ipv4Packet<'p>>

Constructs a new Ipv4Packet. If the provided buffer is less than the minimum required packet size, this will return None.

fn to_immutable<'p>(&'p self) -> Ipv4Packet<'p>

Maps from a Ipv4Packet to a Ipv4Packet

fn minimum_packet_size() -> usize

The minimum size (in bytes) a packet of this type can be. It's based on the total size of the fixed-size fields.

fn packet_size(_packet: &Ipv4) -> usize

The size (in bytes) of a Ipv4 instance when converted into a byte-array

fn get_version(&self) -> u4

Get the version field

fn get_header_length(&self) -> u4

Get the header_length field

fn get_dscp(&self) -> u6

Get the dscp field

fn get_ecn(&self) -> u2

Get the ecn field

fn get_total_length(&self) -> u16be

Get the total_length field

fn get_identification(&self) -> u16be

Get the identification field

fn get_flags(&self) -> u3

Get the flags field

fn get_fragment_offset(&self) -> u13be

Get the fragment_offset field

fn get_ttl(&self) -> u8

Get the ttl field

fn get_next_level_protocol(&self) -> IpNextHeaderProtocol

Get the value of the next_level_protocol field

fn get_checksum(&self) -> u16be

Get the checksum field

fn get_source(&self) -> Ipv4Addr

Get the value of the source field

fn get_destination(&self) -> Ipv4Addr

Get the value of the destination field

fn get_options_raw(&self) -> &[u8]

Get the raw &[u8] value of the options field, without copying

fn get_options(&self) -> Vec<Ipv4Option>

Get the value of the options field (copies contents)

fn get_options_iter(&self) -> Ipv4OptionIterable

Get the value of the options field as iterator

Trait Implementations

impl<'a> PacketSize for Ipv4Packet<'a>

impl<'p> FromPacket for Ipv4Packet<'p>

type T = Ipv4

The type of the packet to convert from

fn from_packet(&self) -> Ipv4

Converts a wire-format packet to #[packet] struct format

impl<'p> Debug for Ipv4Packet<'p>

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

Derived Implementations

impl<'p> PartialEq for Ipv4Packet<'p>

fn eq(&self, __arg_0: &Ipv4Packet<'p>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Ipv4Packet<'p>) -> bool

This method tests for !=.
