SendMessageRequest

Struct SendMessageRequest 

Source
pub struct SendMessageRequest<'a> {
    pub iov: &'a [IoSlice<'a>],
    pub address: Option<&'a SocketAddr>,
    pub fds: &'a [BorrowedFd<'a>],
    pub flags: MessageFlags,
}
Expand description

Requête pour sendmsg(2).

Supporte l’envoi d’un vecteur de buffers et le passage de FDs via le mécanisme SCM_RIGHTS des ancillaires Unix.

Allocation heap : fds est un slice — pas d’allocation ici. La construction des ancillaires en passe 2 se fait sur la pile.

Fields§

§iov: &'a [IoSlice<'a>]

Vecteur de buffers à envoyer.

§address: Option<&'a SocketAddr>

Adresse de destination (pour les sockets non connectés).

§fds: &'a [BorrowedFd<'a>]

FDs à passer au pair via SCM_RIGHTS.

§flags: MessageFlags

Drapeaux de message.
