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.
