Struct tokio::io::Stdout

pub struct Stdout { /* fields omitted */ }

A handle to the standard output stream of a process.

The handle implements the AsyncWrite trait, but beware that concurrent writes to Stdout must be executed with care.

Created by the stdout function.

Trait Implementations

impl Debug for Stdout

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

Formats the value using the given formatter.

impl Write for Stdout

fn write(&mut self, buf: &[u8]) -> Result<usize, Error>

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

Important traits for &'a mut W

impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, 

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.

impl AsyncWrite for Stdout

fn shutdown(&mut self) -> Result<Async<()>, Error>

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

fn poll_write(&mut self, buf: &[u8]) -> Result<Async<usize>, Error>

Attempt to write bytes from buf into the object.

fn poll_flush(&mut self) -> Result<Async<()>, Error>

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

fn write_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where     B: Buf,

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