Struct async_std::io::StdoutLock

pub struct StdoutLock<'a>(_);

This is supported on unstable only.

A locked reference to the Stderr handle.

This handle implements the Write traits, and is constructed via the Stdout::lock method.

Trait Implementations

impl<'_> Write for StdoutLock<'_>

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<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<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<Result<()>> where
    Self: Unpin, 

Writes an entire buffer into the byte stream.

fn write_fmt<'a>(&'a mut self, fmt: Arguments) -> ImplFuture<Result<()>> where
    Self: Unpin, 

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

impl<'_> Send for StdoutLock<'_>

impl<'a> Debug for StdoutLock<'a>

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

Formats the value using the given formatter.
