Struct WriteStream

pub struct WriteStream(/* private fields */);

A stream that can only be written to.

Implementations

impl WriteStream

pub fn id(&self) -> Option<u64>

Returns the stream ID.

pub fn poll_write( &mut self, cx: &mut Context<'_>, buf: &[u8], fin: bool, ) -> Poll<Result<usize, WriteError>>

Poll to write to the stream from buf.

pub fn poll_write_chunk( &mut self, cx: &mut Context<'_>, chunk: &Bytes, fin: bool, ) -> Poll<Result<usize, WriteError>>

Poll to write a bytes to the stream directly.

pub fn write_chunk<'a>( &'a mut self, chunk: &'a Bytes, fin: bool, ) -> WriteChunk<'a>

Write a bytes to the stream directly.

pub fn poll_write_chunks( &mut self, cx: &mut Context<'_>, chunks: &[Bytes], fin: bool, ) -> Poll<Result<usize, WriteError>>

Poll to write the list of bytes to the stream directly.

pub fn write_chunks<'a>( &'a mut self, chunks: &'a [Bytes], fin: bool, ) -> WriteChunks<'a>

Write the list of bytes to the stream directly.

pub fn poll_finish_write( &mut self, cx: &mut Context<'_>, ) -> Poll<Result<(), WriteError>>

Poll to finish writing to the stream.

pub fn poll_abort_write( &mut self, cx: &mut Context<'_>, error_code: u64, ) -> Poll<Result<(), WriteError>>

Poll to abort writing to the stream.

pub fn abort_write(&mut self, error_code: u64) -> Result<(), WriteError>

Abort writing to the stream.

Trait Implementations

impl AsyncWrite for WriteStream

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

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

Attempts to flush the object, ensuring that any buffered data reach their destination.

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

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl AsyncWrite for WriteStream

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

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

Attempt to flush the object, ensuring that any buffered data reach their destination.

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

Attempt to close the object.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

impl Debug for WriteStream

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

Formats the value using the given formatter.
