Implementations

impl<T, S> WriteVectoredAt<T, S>

where T: IoVectoredBuf,

pub fn new(fd: S, offset: u64, buffer: T) -> WriteVectoredAt<T, S>

Create WriteVectoredAt.

Trait Implementations

impl<T, S> IntoInner for WriteVectoredAt<T, S>

where T: IoVectoredBuf,

type Inner = T

The inner type.

fn into_inner(self) -> <WriteVectoredAt<T, S> as IntoInner>::Inner

Get the inner buffer.

impl<T, S> OpCode for WriteVectoredAt<T, S>

where T: IoVectoredBuf, S: AsFd,

type Control = AioControl<VectoredControl>

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

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

Initialize the control

fn pre_submit( &mut self, ctrl: &mut <WriteVectoredAt<T, 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, ctrl: &mut <WriteVectoredAt<T, S> as OpCode>::Control, ) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate( &mut self, ctrl: &mut <WriteVectoredAt<T, 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, _: &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.
