Struct RecvManaged 

pub struct RecvManaged<S> { /* private fields */ }

Receive data from remote into managed buffer.

It is only used for socket operations. If you want to read from a pipe, use ReadManaged.

Implementations

impl<S> RecvManaged<S>

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

Create RecvManaged.

pub fn poll_first(&mut self)

This method sets the IORING_RECVSEND_POLL_FIRST flag in the ioprio of the SQE on the IO_URING driver.

Trait Implementations

impl<S> OpCode for RecvManaged<S>

where S: AsFd,

type Control = ()

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

fn pre_submit( &mut self, control: &mut <RecvManaged<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 <RecvManaged<S> as OpCode>::Control, ) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate( &mut self, control: &mut <RecvManaged<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 init(&mut self, _: &mut Self::Control)

Initialize the control

unsafe fn set_result( &mut self, _: &mut Self::Control, _: &Result<usize, Error>, _: &Extra, )

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

impl<S> TakeBuffer for RecvManaged<S>

type Buffer = BufferRef

Type of the buffer.

fn take_buffer(self) -> Option<BufferRef>

Take buffer.
