Struct ReadVectored 

pub struct ReadVectored<T: IoVectoredBufMut, S> { /* private fields */ }

Available on Unix only.

Receive a file into vectored buffer.

Implementations

impl<T: IoVectoredBufMut, S> ReadVectored<T, S>

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

Create ReadVectored.

Trait Implementations

impl<T: IoVectoredBufMut, S> IntoInner for ReadVectored<T, S>

type Inner = T

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<T: IoVectoredBufMut, S: AsFd> OpCode for ReadVectored<T, S>

fn pre_submit(self: Pin<&mut Self>) -> Result<Decision>

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

fn op_type(self: Pin<&mut Self>) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate(self: Pin<&mut Self>) -> Poll<Result<usize>>

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

impl<T: IoVectoredBufMut, S: AsFd> OpCode for ReadVectored<T, S>

fn create_entry(self: Pin<&mut Self>) -> OpEntry

Create submission entry.

fn call_blocking(self: Pin<&mut Self>) -> Result<usize>

Call the operation in a blocking way. This method will only be called if create_entry returns OpEntry::Blocking.

unsafe fn set_result(self: Pin<&mut Self>, _: usize)

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