Struct async_std::io::Stdout

pub struct Stdout(_);

A handle to the standard output of the current process.

Created by the stdout function.

This type is an async version of std::io::Stdout.

Trait Implementations

impl Write for Stdout

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>>

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

fn write<'a>(&'a mut self, buf: &'a [u8]) -> ImplFuture<'a, Result<usize>> where
    Self: Unpin, 

Writes some bytes into the byte stream.

fn flush(&mut self) -> ImplFuture<Result<()>> where
    Self: Unpin, 

Flushes the stream to ensure that all buffered contents reach their destination.

fn write_vectored<'a>(
    &'a mut self,
    bufs: &'a [IoSlice<'a>]
) -> ImplFuture<'a, Result<usize>> where
    Self: Unpin, 

Like [write], except that it writes from a slice of buffers.

fn write_all<'a>(&'a mut self, buf: &'a [u8]) -> ImplFuture<'a, Result<()>> where
    Self: Unpin, 

Writes an entire buffer into the byte stream.

impl AsRawFd for Stdout

fn as_raw_fd(&self) -> RawFd

This is supported on Unix only.

Extracts the raw file descriptor.

impl AsRawHandle for Stdout

fn as_raw_handle(&self) -> RawHandle

This is supported on Windows only.

Extracts the raw handle, without taking any ownership.

impl Debug for Stdout

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

Formats the value using the given formatter.
