Implementations

impl DhcpOption

pub fn new(code: u8, data: Vec<u8>) -> Self

pub fn message_type(msg_type: u8) -> Self

Create a message type option.

pub fn server_id(ip: Ipv4Addr) -> Self

Create a server identifier option.

pub fn lease_time(seconds: u32) -> Self

Create a lease time option.

pub fn subnet_mask(mask: Ipv4Addr) -> Self

Create a subnet mask option.

pub fn router(ip: Ipv4Addr) -> Self

Create a router option.

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

Create a DNS servers option.

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

Create a domain name option.

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

Serialize this option to bytes.

pub fn as_message_type(&self) -> Option<u8>

pub fn as_ipv4(&self) -> Option<Ipv4Addr>

Get an IPv4 address value (for 4-byte options like subnet mask, router, etc).

Trait Implementations

impl Clone for DhcpOption

fn clone(&self) -> DhcpOption

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DhcpOption

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DhcpOption

fn eq(&self, other: &DhcpOption) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
