pub struct Io { /* fields omitted */ }

Async io stream

Methods

impl Io

pub fn create() -> (Io, Io)

Create a two interconnected streams

pub fn is_client_dropped(&self) -> bool

pub fn is_server_dropped(&self) -> bool

pub fn is_closed(&self) -> bool

Check if channel is closed from remoote side

pub fn read_pending(&self)

Set read to Pending state

pub fn read_error(&self, err: Error)

Set read to error

pub fn local_buffer<F, R>(&self, f: F) -> R where
    F: FnOnce(&mut BytesMut) -> R, 

Access read buffer.

pub fn remote_buffer<F, R>(&self, f: F) -> R where
    F: FnOnce(&mut BytesMut) -> R, 

Access remote buffer.

pub async fn close<'_>(&'_ self)

Closed remote side.

pub fn write<T: AsRef<[u8]>>(&self, data: T)

Add extra data to the remote buffer and notify reader

pub fn remote_buffer_cap(&self, cap: usize)

Read any available data

pub fn read_any(&self) -> BytesMut

Read any available data

pub async fn read<'_>(&'_ self) -> Result<BytesMut, Error>

Read data, if data is not available wait for it

Trait Implementations

impl AsyncRead for Io

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

Attempts to read from the AsyncRead into buf.

unsafe fn prepare_uninitialized_buffer(
    &self,
    buf: &mut [MaybeUninit<u8>]
) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

fn poll_read_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: BufMut, 

Pulls some bytes from this source into the specified BufMut, returning how many bytes were read.

impl AsyncWrite for Io

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>, _: &mut Context) -> Poll<Result<()>>

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

fn poll_shutdown(self: Pin<&mut Self>, _: &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_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: Buf, 

Writes a Buf into this value, returning how many bytes were written.

impl Clone for Io

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Io

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

Formats the value using the given formatter.

impl Drop for Io

fn drop(&mut self)

Executes the destructor for this type.
