Struct MsgHdr 

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

Available on non-Redox only.

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) -> 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
