Struct etherparse::PacketBuilder

pub struct PacketBuilder {}

Helper for building packets.

The packet builder allows the easy construction of a packet from the ethernet II layer downwards including ipv6, ipv4, the udp header and the actual payload. The packet builder automatically calculates lengths & checksums for ip & udp and set type identifiers for ethernetII and ip. This makes it easy and less error prone to construct custom packets.

Example

let builder = PacketBuilder::
    ethernet2([1,2,3,4,5,6],     //source mac
              [7,8,9,10,11,12]) //destionation mac
   .ipv4([192,168,1,1], //source ip
         [192,168,1,2], //desitionation ip
         20)            //time to life
   .udp(21,    //source port 
        1234); //desitnation port

//payload of the udp packet
let payload = [1,2,3,4,5,6,7,8];
     
//get some memory to store the result
let mut result = Vec::<u8>::with_capacity(
                    builder.size(payload.len()));
     
//serialize
builder.write(&mut result, &payload).unwrap();
println!("{:?}", result);

Implementations

impl PacketBuilder

pub fn ethernet2(
    source: [u8; 6],
    destination: [u8; 6]
) -> PacketBuilderStep<Ethernet2Header>

Start an packet with an ethernetII header.
