pub struct MsgHdrMut<'addr, 'bufs, 'control> { /* private fields */ }Expand description
Configuration of a recvmsg(2) system call.
This wraps msghdr on Unix and WSAMSG on Windows. Also see MsgHdr for
the variant used by sendmsg(2).
Implementations§
Source§impl<'addr, 'bufs, 'control> MsgHdrMut<'addr, 'bufs, 'control>
impl<'addr, 'bufs, 'control> MsgHdrMut<'addr, 'bufs, 'control>
Sourcepub fn new() -> MsgHdrMut<'addr, 'bufs, 'control>
pub fn new() -> MsgHdrMut<'addr, 'bufs, 'control>
Create a new MsgHdrMut with all empty/zero fields.
Sourcepub fn with_addr(
self,
addr: &'addr mut SockAddr,
) -> MsgHdrMut<'addr, 'bufs, 'control>
pub fn with_addr( self, addr: &'addr mut SockAddr, ) -> MsgHdrMut<'addr, 'bufs, 'control>
Set the mutable address (name) of the message.
Corresponds to setting msg_name and msg_namelen on Unix and name
and namelen on Windows.
Sourcepub fn with_buffers(
self,
bufs: &'bufs mut [MaybeUninitSlice<'_>],
) -> MsgHdrMut<'addr, 'bufs, 'control>
pub fn with_buffers( self, bufs: &'bufs mut [MaybeUninitSlice<'_>], ) -> MsgHdrMut<'addr, 'bufs, 'control>
Set the mutable buffer(s) of the message.
Corresponds to setting msg_iov and msg_iovlen on Unix and lpBuffers
and dwBufferCount on Windows.
Sourcepub fn with_control(
self,
buf: &'control mut [MaybeUninit<u8>],
) -> MsgHdrMut<'addr, 'bufs, 'control>
pub fn with_control( self, buf: &'control mut [MaybeUninit<u8>], ) -> MsgHdrMut<'addr, 'bufs, 'control>
Set the mutable control buffer of the message.
Corresponds to setting msg_control and msg_controllen on Unix and
Control on Windows.
Sourcepub fn control_len(&self) -> usize
pub fn control_len(&self) -> usize
Gets the length of the control buffer.
Can be used to determine how much, if any, of the control buffer was filled by recvmsg.
Corresponds to msg_controllen on Unix and Control.len on Windows.
