Struct socket2::MsgHdr

pub struct MsgHdr<'addr, 'bufs, 'control> {
    pub(crate) inner: msghdr,
    pub(crate) _lifetimes: PhantomData<(&'addr SockAddr, &'bufs IoSlice<'bufs>, &'control [u8])>,
}

Configuration of a sendmsg(2) system call.

This wraps msghdr on Unix and WSAMSG on Windows. Also see MsgHdrMut for the variant used by recvmsg(2).

Fields

inner: msghdr

_lifetimes: PhantomData<(&'addr SockAddr, &'bufs IoSlice<'bufs>, &'control [u8])>

Implementations

impl<'addr, 'bufs, 'control> MsgHdr<'addr, 'bufs, 'control>

pub fn new() -> MsgHdr<'addr, 'bufs, 'control>

Create a new MsgHdr with all empty/zero fields.

pub fn with_addr(self, addr: &'addr SockAddr) -> Self

Set the address (name) of the message.

Corresponds to setting msg_name and msg_namelen on Unix and name and namelen on Windows.

pub fn with_buffers(self, bufs: &'bufs [IoSlice<'_>]) -> Self

Set the buffer(s) of the message.

Corresponds to setting msg_iov and msg_iovlen on Unix and lpBuffers and dwBufferCount on Windows.

pub fn with_control(self, buf: &'control [u8]) -> Self

Set the control buffer of the message.

Corresponds to setting msg_control and msg_controllen on Unix and Control on Windows.

pub fn with_flags(self, flags: c_int) -> Self

Set the flags of the message.

Corresponds to setting msg_flags on Unix and dwFlags on Windows.

Trait Implementations

impl<'name, 'bufs, 'control> Debug for MsgHdr<'name, 'bufs, 'control>

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

Formats the value using the given formatter.
