Struct varu64::Encode

pub struct Encode<W> { /* fields omitted */ }

A future for encoding a u64 into an AsyncWrite.

Methods

impl<W> Encode<W>

pub fn new(writer: W, int: u64) -> Encode<W>

Create a new Encode future for encoding the given u64 into the given W.

Trait Implementations

impl<W: AsyncWrite> Future for Encode<W>

type Item = (W, usize)

The wrapped W, and how many bytes were written into the W.

type Error = (W, FutError)

Propagated from writing, or an error of kind "WriteZero" if a call to poll_write returned 0 even though not all data has been written.

fn poll(&mut self, cx: &mut Context) -> Poll<Self::Item, Self::Error>

Note that this does not flush or close the wrapped W.

impl<W> AsyncWriterFuture<W> for Encode<W> where
    W: AsyncWrite, 

fn already_written(&self) -> usize

Return how many bytes have already been written.

impl<W> AsyncWriterFutureLen<W> for Encode<W> where
    W: AsyncWrite, 

fn remaining_bytes(&self) -> usize

Compute the exact number of bytes that will still be written by this future.

impl<W> AsyncSerialize<W> for Encode<W> where
    W: AsyncWrite, 

type Serialized = u64

The type of values serialized.

fn from_val(writer: W, val: Self::Serialized) -> Self

Create a new instance, consuming the value to serialize and wrapping the AsyncWrite to serialize into.

impl<W> AsyncSerializeLen<W> for Encode<W> where
    W: AsyncWrite, 

fn total_bytes(val: &Self::Serialized) -> usize

Compute the exact number of bytes that would be written in total if the given value was serialized.
