Struct IpMembershipV4 

#[repr(C)]
pub struct IpMembershipV4 {
    pub multiaddr: [u8; 4],
    pub interface: [u8; 4],
}

Adhésion à un groupe multicast IPv4 — struct ip_mreq du kernel.

Argument de setsockopt(IP_ADD_MEMBERSHIP / IP_DROP_MEMBERSHIP). Layout #[repr(C)] fidèle à l’ABI : deux struct in_addr accolées (chacune un __be32, ordre réseau), soit 8 octets sans rembourrage (assertion de taille en test). Type dédié (ADR-021) — jamais d’octets bruts exposés.

Fields

multiaddr: [u8; 4]

Adresse du groupe multicast (imr_multiaddr, ordre réseau big-endian).

interface: [u8; 4]

Adresse de l’interface locale (imr_interface, ordre réseau) ; [0, 0, 0, 0] = INADDR_ANY (le kernel choisit via la table de routage).
