Struct async_bincode::AsyncBincodeWriter

pub struct AsyncBincodeWriter<W, T, D> { /* fields omitted */ }

A wrapper around an asynchronous sink that accepts, serializes, and sends bincode-encoded values.

To use, provide a writer that implements AsyncWrite, and then use Sink to send values.

Note that an AsyncBincodeWriter must be of the type AsyncDestination in order to be compatible with an [AsyncBincodeReader] on the remote end (recall that it requires the serialized size prefixed to the serialized data). The default is SyncDestination, but these can be easily toggled between using AsyncBincodeWriter::for_async.

Implementations

impl<W, T, D> AsyncBincodeWriter<W, T, D>

pub fn get_ref(&self) -> &W

Gets a reference to the underlying writer.

It is inadvisable to directly write to the underlying writer.

pub fn get_mut(&mut self) -> &mut W

Gets a mutable reference to the underlying writer.

It is inadvisable to directly write to the underlying writer.

pub fn into_inner(self) -> W

Unwraps this AsyncBincodeWriter, returning the underlying writer.

Note that any leftover serialized data that has not yet been sent is lost.

impl<W, T> AsyncBincodeWriter<W, T, SyncDestination>

pub fn for_async(self) -> AsyncBincodeWriter<W, T, AsyncDestination>

Make this writer include the serialized data's size before each serialized value.

This is necessary for compatability with [AsyncBincodeReader].

impl<W, T> AsyncBincodeWriter<W, T, AsyncDestination>

pub fn for_sync(self) -> AsyncBincodeWriter<W, T, SyncDestination>

Make this writer only send bincode-encoded values.

This is necessary for compatability with stock bincode receivers.

Trait Implementations

impl<W: Debug, T: Debug, D: Debug> Debug for AsyncBincodeWriter<W, T, D>

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

Formats the value using the given formatter.

impl<W, T> Default for AsyncBincodeWriter<W, T, SyncDestination> where
    W: Default, 

pub fn default() -> Self

Returns the "default value" for a type.

impl<W, T> From<W> for AsyncBincodeWriter<W, T, SyncDestination>

pub fn from(writer: W) -> Self

Performs the conversion.

impl<W, T, D> Sink<T> for AsyncBincodeWriter<W, T, D> where
    T: Serialize,
    W: AsyncWrite + Unpin,
    Self: BincodeWriterFor<T>, 

type Error = Error

The type of value produced by the sink when an error occurs.

pub fn poll_ready(
    self: Pin<&mut Self>,
    _: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

pub fn start_send(mut self: Pin<&mut Self>, item: T) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

pub fn poll_flush(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

pub fn poll_close(
    mut self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<W, T, D> Unpin for AsyncBincodeWriter<W, T, D> where
    W: Unpin,
