Struct Recv 

pub struct Recv<T: IoBufMut, S> { /* private fields */ }

Receive data from remote.

If you want to read from a pipe, use Read.

Implementations

impl<T: IoBufMut, S> Recv<T, S>

pub fn new(fd: S, buffer: T, flags: RecvFlags) -> Self

Create Recv.

Trait Implementations

impl<T: IoBufMut, S> IntoInner for Recv<T, S>

type Inner = T

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<T: IoBufMut, S: AsFd> OpCode for Recv<T, S>

type Control = ()

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

fn create_entry(&mut self, _: &mut Self::Control) -> OpEntry

Create submission entry.

fn call_blocking(&mut self, _: &mut Self::Control) -> Result<usize>

Call the operation in a blocking way. This method will be called if

unsafe fn init(&mut self, _: &mut Self::Control)

Initialize the control

fn create_entry_fallback(&mut self, _: &mut Self::Control) -> OpEntry

Create submission entry for fallback. This method will only be called if create_entry returns an entry with unsupported opcode.

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

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

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

Push a multishot result to the inner queue.

fn pop_multishot( &mut self, _: &mut Self::Control, ) -> Option<BufResult<usize, Extra>>

Pop a multishot result from the inner queue.

impl<T: IoBufMut, S: AsFd> OpCode for Recv<T, S>

type Control = ()

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

fn pre_submit(&mut self, _: &mut Self::Control) -> Result<Decision>

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

fn op_type(&mut self, _: &mut Self::Control) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate(&mut self, _: &mut Self::Control) -> Poll<Result<usize>>

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>, _: &Extra, )

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