Struct StrongWriter 

pub struct StrongWriter { /* private fields */ }

Writer that maintains a persistent tail slot and participates in backpressure accounting.

Implementations

impl StrongWriter

pub fn writable_size(&self) -> u64

Current number of bytes the writer can append without blocking.

pub fn terminate(&mut self)

Safely terminate this writer.

This will cause poll_write to error with std::io::ErrorKind::ConnectionAborted.

pub fn downgrade(self) -> WeakWriter

Convert this strong writer into a weak writer that relinquishes its tail slot when idle.

Trait Implementations

impl AsyncWrite for StrongWriter

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 Drop for StrongWriter

fn drop(&mut self)

Executes the destructor for this type.
