Implementations

impl<'buffer, 'input> Ipv4PacketBuilder<'buffer, 'input>

pub fn new(buffer: &'buffer mut [u8], payload: usize) -> Self

Starts a builder with untouched payload bytes.

pub fn source(self, v: Ipv4Address) -> Self

Supplies source.

pub fn destination(self, v: Ipv4Address) -> Self

Supplies destination.

pub fn protocol(self, v: Ipv4Protocol) -> Self

Supplies protocol.

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

Supplies TTL.

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

Supplies identification.

pub fn flags_fragment_offset(self, v: u16) -> Self

Supplies flags and offset.

pub fn dscp_ecn(self, v: u8) -> Self

Supplies DSCP/ECN.

pub fn options(self, v: &'input [u8]) -> Self

Supplies copied options.

pub fn build(self) -> Result<Ipv4PacketMut<'buffer>, Ipv4PacketBuildError>

Validates before all writes, writes/header-checksums only the header, and preserves payload and trailing capacity.
