Struct completion_io::DefaultWriteVectored

pub struct DefaultWriteVectored<'a, T: AsyncWriteWith<'a>> { /* fields omitted */ }

A default implementation of WriteVectoredFuture for types that don't have efficient vectored writes.

This will forward to write with the first nonempty buffer provided, or an empty one if none exists.

Implementations

impl<'a, T: AsyncWriteWith<'a>> DefaultWriteVectored<'a, T>

pub fn new(writer: &'a mut T, bufs: &'a [IoSlice<'a>]) -> Self

Create a new DefaultWriteVectored future.

Trait Implementations

impl<'a, T: AsyncWriteWith<'a>> CompletionFuture for DefaultWriteVectored<'a, T>

type Output = Result<usize>

The type of value produced on completion.

unsafe fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

unsafe fn poll_cancel(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<()>

Attempt to cancel the future, registering the current task for wakeup if has not finished cancelling yet.

impl<'a, T: Debug + AsyncWriteWith<'a>> Debug for DefaultWriteVectored<'a, T> where
    T::WriteFuture: Debug, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: AsyncWriteWith<'a>> Future for DefaultWriteVectored<'a, T> where
    <T as AsyncWriteWith<'a>>::WriteFuture: Future<Output = Result<usize>>, 

type Output = Result<usize>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
