Struct IPv4EndpointOptionRepr 

pub struct IPv4EndpointOptionRepr {
    pub ipv4_address: [u8; 4],
    pub protocol: TransportProtocol,
    pub port: u16,
}

High-level representation of an IPv4 Endpoint Option.

This provides a builder-style API for constructing and parsing IPv4 endpoint options without manually managing byte arrays.

Fields

ipv4_address: [u8; 4]

IPv4 address (4 bytes)

protocol: TransportProtocol

Transport protocol (TCP=0x06, UDP=0x11)

port: u16

Port number

Implementations

impl IPv4EndpointOptionRepr

pub fn parse<T: AsRef<[u8]>>(option: &IPv4EndpointOption<T>) -> Result<Self>

Parse an IPv4EndpointOption into a high-level representation.

Parameters

• option - The IPv4EndpointOption to parse

Returns

IPv4EndpointOptionRepr with all fields populated

Errors

Returns Error::InvalidProtocol if protocol is not TCP or UDP

pub fn emit(&self, buffer: &mut [u8]) -> usize

Emit this representation into a buffer.

Parameters

• buffer - 12-byte buffer to write the option into

Returns

Number of bytes written (always 12)

pub const fn buffer_len() -> usize

Get the wire format size of this option (always 12 bytes: 4 header + 8 payload).

Trait Implementations

impl Clone for IPv4EndpointOptionRepr

fn clone(&self) -> IPv4EndpointOptionRepr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IPv4EndpointOptionRepr

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

Formats the value using the given formatter.

impl PartialEq for IPv4EndpointOptionRepr

fn eq(&self, other: &IPv4EndpointOptionRepr) -> 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.
