Struct IgmpMessage 

pub struct IgmpMessage {
    pub msg_type: u8,
    pub max_resp_time: u8,
    pub checksum: u16,
    pub group_address: [u8; 4],
}

IGMPv2 message (8 bytes on the wire)

Fields

msg_type: u8

Message type (0x11 = Query, 0x16 = Report, 0x17 = Leave)

max_resp_time: u8

Maximum response time (in 1/10 second units)

checksum: u16

Internet checksum over the entire IGMP message

group_address: [u8; 4]

Group address (0.0.0.0 for general queries)

Implementations

impl IgmpMessage

pub const WIRE_SIZE: usize = 8usize

Size of a serialized IGMP message in bytes.

pub fn new(msg_type: u8, max_resp_time: u8, group_address: [u8; 4]) -> Self

Create a new IGMP message with checksum computed automatically.

pub fn to_bytes(&self) -> [u8; 8]

Serialize the message to bytes.

pub fn from_bytes(data: &[u8]) -> Result<Self, MulticastError>

Deserialize from bytes.

pub fn compute_checksum(&self) -> u16

Compute the Internet checksum over the IGMP message.

pub fn verify_checksum(&self) -> bool

Verify the message checksum.

Trait Implementations

impl Clone for IgmpMessage

fn clone(&self) -> IgmpMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IgmpMessage

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

Formats the value using the given formatter.

impl PartialEq for IgmpMessage

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