Struct MMsgHdr 

#[repr(transparent)]
pub struct MMsgHdr<'a> {
    raw: mmsghdr,
    _phantom: PhantomData<&'a mut ()>,
}

An ABI-compatible wrapper for mmsghdr, for sending multiple messages with sendmmsg.

Fields

raw: mmsghdr

_phantom: PhantomData<&'a mut ()>

Implementations

impl<'a> MMsgHdr<'a>

pub fn new( iov: &'a [IoSlice<'_>], control: &'a mut SendAncillaryBuffer<'_, '_, '_>, ) -> Self

Constructs a new message with no destination address.

pub fn new_with_addr( addr: &'a SocketAddrAny, iov: &'a [IoSlice<'_>], control: &'a mut SendAncillaryBuffer<'_, '_, '_>, ) -> Self

Constructs a new message to a specific address.

This requires a SocketAddrAny instead of using impl SocketAddrArg; to obtain a SocketAddrAny, use SocketAddrArg::as_any.

fn wrap(msg_hdr: msghdr) -> Self

pub fn bytes_sent(&self) -> usize

Returns the number of bytes sent. This will return 0 until after a successful call to sendmmsg.
