Struct Ipv4PacketBuilder 

pub struct Ipv4PacketBuilder { /* private fields */ }

Builder for IPv4 packets.

Implementations

pub fn identification(self, id: u16) -> Self

pub fn dont_fragment(self, df: bool) -> Self

pub fn more_fragments(self, mf: bool) -> Self

pub fn fragment_offset(self, offset: u16) -> Self

pub fn ttl(self, ttl: u8) -> Self

pub fn protocol(self, proto: IpProtocol) -> Self

pub fn source(self, addr: Ipv4Addr) -> Self

pub fn destination(self, addr: Ipv4Addr) -> Self

pub fn payload(self, data: &[u8]) -> Result<Self, BuildError>

pub fn build(self) -> Vec<u8>
