Struct MsgHdr 

pub struct MsgHdr<'addr, 'bufs, 'control> { /* private fields */ }

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).

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) -> MsgHdr<'addr, 'bufs, 'control>

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<'_>], ) -> MsgHdr<'addr, 'bufs, 'control>

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]) -> MsgHdr<'addr, 'bufs, 'control>

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: i32) -> MsgHdr<'addr, 'bufs, 'control>

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<(), Error>

Formats the value using the given formatter.
