Struct RecvMsgManaged 

pub struct RecvMsgManaged<C, S>
where
    C: IoBufMut,
    S: AsFd,
{ /* private fields */ }

Receive data into managed buffer, and ancillary data into control buffer.

Implementations

impl<C, S> RecvMsgManaged<C, S>

where C: IoBufMut, S: AsFd,

pub fn new( fd: S, pool: &BufferPool, len: usize, control: C, flags: RecvFlags, ) -> Result<RecvMsgManaged<C, S>, Error>

Create RecvMsgManaged.

Trait Implementations

impl<C, S> OpCode for RecvMsgManaged<C, S>

where C: IoBufMut, S: AsFd,

type Control = RecvMsgControl

Type that contains self-references and other needed info during the operation

unsafe fn init(&mut self, ctrl: &mut <RecvMsgManaged<C, S> as OpCode>::Control)

Initialize the control

fn pre_submit( &mut self, control: &mut <RecvMsgManaged<C, S> as OpCode>::Control, ) -> Result<Decision, Error>

Perform the operation before submit, and return Decision to indicate whether submitting the operation to polling is required.

fn op_type( &mut self, control: &mut <RecvMsgManaged<C, S> as OpCode>::Control, ) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate( &mut self, control: &mut <RecvMsgManaged<C, S> as OpCode>::Control, ) -> Poll<Result<usize, Error>>

Perform the operation after received corresponding event. If this operation is blocking, the return value should be Poll::Ready.

unsafe fn set_result( &mut self, control: &mut <RecvMsgManaged<C, S> as OpCode>::Control, result: &Result<usize, Error>, extra: &Extra, )

Set the result when it completes. The operation stores the result and is responsible to release it if the operation is cancelled.

impl<C, S> PollFirst for RecvMsgManaged<C, S>

where C: IoBufMut, S: AsFd,

fn poll_first(&mut self)

Poll first before syscall. This is only meaningful for io-uring. It sets IORING_RECVSEND_POLL_FIRST flag in the ioprio of the SQE.

impl<C, S> TakeBuffer for RecvMsgManaged<C, S>

where C: IoBufMut, S: AsFd,

type Buffer = ((BufferRef, C), Option<SockAddr>, usize, ReturnFlags)

Type of the buffer.

fn take_buffer(self) -> Option<<RecvMsgManaged<C, S> as TakeBuffer>::Buffer>

Take buffer.
