Struct IgmpPacket

pub struct IgmpPacket<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around an Internet Group Management Protocol v1/v2 packet buffer.

Implementations

impl<T: AsRef<[u8]>> Packet<T>

Internet Group Management Protocol v1/v2 defined in RFC 2236.

pub const fn new_unchecked(buffer: T) -> Packet<T>

Imbue a raw octet buffer with IGMPv2 packet structure.

pub fn new_checked(buffer: T) -> Result<Packet<T>>

Shorthand for a combination of new_unchecked and check_len.

pub fn check_len(&self) -> Result<()>

Ensure that no accessor method will panic if called. Returns Err(Error) if the buffer is too short.

pub fn into_inner(self) -> T

Consume the packet, returning the underlying buffer.

pub fn msg_type(&self) -> Message

Return the message type field.

pub fn max_resp_code(&self) -> u8

Return the maximum response time, using the encoding specified in RFC 3376: 4.1.1. Max Resp Code.

pub fn checksum(&self) -> u16

Return the checksum field.

pub fn group_addr(&self) -> Ipv4Address

Return the source address field.

pub fn verify_checksum(&self) -> bool

Validate the header checksum.

Fuzzing

This function always returns true when fuzzing.

impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>

pub fn set_msg_type(&mut self, value: Message)

Set the message type field.

pub fn set_max_resp_code(&mut self, value: u8)

Set the maximum response time, using the encoding specified in [RFC 3376]: 4.1.1. Max Resp Code.

pub fn set_checksum(&mut self, value: u16)

Set the checksum field.

pub fn set_group_address(&mut self, addr: Ipv4Address)

Set the group address field

pub fn fill_checksum(&mut self)

Compute and fill in the header checksum.
