Struct CopyToBytes

pub struct CopyToBytes<S> { /* private fields */ }

A helper that wraps a Sink<Bytes> and converts it into a Sink<&'a [u8]> by copying each byte slice into an owned Bytes.

See the documentation for SinkWriter for an example.

Implementations

impl<S> CopyToBytes<S>

pub fn new(inner: S) -> Self

Creates a new CopyToBytes.

pub fn get_ref(&self) -> &S

Gets a reference to the underlying sink.

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

Gets a mutable reference to the underlying sink.

pub fn into_inner(self) -> S

Consumes this CopyToBytes, returning the underlying sink.

Trait Implementations

impl<S: Debug> Debug for CopyToBytes<S>

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

Formats the value using the given formatter.

impl<'a, S> Sink<&'a [u8]> for CopyToBytes<S>

where S: Sink<Bytes>,

type Error = <S as Sink<Bytes>>::Error

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

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

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: &'a [u8]) -> 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(())).

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

Flush any remaining output from this sink.

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

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

impl<S: Stream> Stream for CopyToBytes<S>

type Item = <S as Stream>::Item

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<'__pin, S> Unpin for CopyToBytes<S>

where PinnedFieldsOf<__Origin<'__pin, S>>: Unpin,
