Struct netsim::wire::Ipv4Packet

pub struct Ipv4Packet { /* fields omitted */ }

An Ipv4 packet.

Methods

impl Ipv4Packet

fn new_from_fields(fields: Ipv4Fields, payload: &Ipv4Payload) -> Ipv4Packet

Create a new Ipv4Packet with the given header fields and payload. If you are also creating the packet's payload data it can be more efficient to use new_from_fields_recursive and save an allocation/copy.

fn new_from_fields_recursive(
    fields: Ipv4Fields,
    payload_fields: Ipv4PayloadFields
) -> Ipv4Packet

Create a new Ipv4Packet with the given header fields and payload fields.

fn write_to_buffer(
    buffer: &mut [u8],
    fields: Ipv4Fields,
    payload_fields: Ipv4PayloadFields
)

Create a new Ipv4 packet by writing it to the given empty buffer.

fn from_bytes(buffer: Bytes) -> Ipv4Packet

Parse an Ipv4 packet from the given buffer.

fn fields(&self) -> Ipv4Fields

Get the header of fields of this packet.

fn set_fields(&mut self, fields: Ipv4Fields)

Set the packet's header fields.

fn source_ip(&self) -> Ipv4Addr

Get the source Ipv4 address.

fn dest_ip(&self) -> Ipv4Addr

Get the destination Ipv4 address.

fn ttl(&self) -> u8

Get the hop count/time-to-live of this packet.

fn payload(&self) -> Ipv4Payload

Get the packet's payload

fn as_bytes(&self) -> &Bytes

Returns the underlying packet data.

fn verify_checksum(&self) -> bool

Check that this packet has a valid checksum.

Trait Implementations
