Struct DhcpBuilder 

pub struct DhcpBuilder { /* private fields */ }

Builder for constructing DHCP packets.

Implementations

impl DhcpBuilder

pub fn new() -> Self

pub fn discover(client_mac: MacAddress, xid: u32) -> Self

Create a DHCP Discover message.

pub fn offer( xid: u32, client_mac: MacAddress, offered_ip: Ipv4Addr, server_ip: Ipv4Addr, ) -> Self

Create a DHCP Offer message.

pub fn request( client_mac: MacAddress, xid: u32, requested_ip: Ipv4Addr, server_ip: Ipv4Addr, ) -> Self

Create a DHCP Request message.

pub fn ack( xid: u32, client_mac: MacAddress, assigned_ip: Ipv4Addr, server_ip: Ipv4Addr, ) -> Self

Create a DHCP ACK message.

pub fn nak(xid: u32, client_mac: MacAddress, server_ip: Ipv4Addr) -> Self

Create a DHCP NAK message.

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

pub fn xid(self, xid: u32) -> Self

pub fn flags(self, flags: u16) -> Self

pub fn ciaddr(self, ip: Ipv4Addr) -> Self

pub fn yiaddr(self, ip: Ipv4Addr) -> Self

pub fn siaddr(self, ip: Ipv4Addr) -> Self

pub fn giaddr(self, ip: Ipv4Addr) -> Self

pub fn chaddr_mac(self, mac: MacAddress) -> Self

pub fn option(self, opt: DhcpOption) -> Self

Add a DHCP option.

pub fn lease_time(self, seconds: u32) -> Self

Add a lease time option.

pub fn subnet_mask(self, mask: Ipv4Addr) -> Self

Add a subnet mask option.

pub fn router(self, ip: Ipv4Addr) -> Self

Add a router option.

pub fn dns(self, servers: &[Ipv4Addr]) -> Self

Add a DNS servers option.

pub fn domain_name(self, name: &str) -> Self

Add a domain name option.

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

Build the DHCP packet bytes (BOOTP header + options).

This produces the UDP payload — the caller must wrap it in UDP(sport=67, dport=68) / IP / Ethernet.
