Struct tokio_util::io::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.
