Struct tokio::io::Stdout [−][src]
pub struct Stdout { /* fields omitted */ }
io-std
only.Expand description
A handle to the standard output stream of a process.
Concurrent writes to stdout must be executed with care: Only individual
writes to this AsyncWrite
are guaranteed to be intact. In particular
you should be aware that writes using write_all
are not guaranteed
to occur as a single write, so multiple threads writing data with
write_all
may result in interleaved output.
Created by the stdout
function.
Examples
use tokio::io::{self, AsyncWriteExt}; #[tokio::main] async fn main() -> io::Result<()> { let mut stdout = io::stdout(); stdout.write_all(b"Hello world!").await?; Ok(()) }

[src]
impl AsRawHandle for Stdout
[src]fn as_raw_handle(&self) -> RawHandle
[src]
fn as_raw_handle(&self) -> RawHandle
[src]Extracts the raw handle, without taking any ownership.
impl AsyncWrite for Stdout
[src]
impl AsyncWrite for Stdout
[src]fn poll_write(
self: Pin<&mut Self>,
cx: &mut Context<'_>,
buf: &[u8]
) -> Poll<Result<usize>>
[src]
fn poll_write(
self: Pin<&mut Self>,
cx: &mut Context<'_>,
buf: &[u8]
) -> Poll<Result<usize>>
[src]Attempt to write bytes from buf
into the object. Read more
fn poll_flush(
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Result<(), Error>>
[src]
fn poll_flush(
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Result<(), Error>>
[src]Attempts to flush the object, ensuring that any buffered data reach their destination. Read more
fn poll_shutdown(
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Result<(), Error>>
[src]
fn poll_shutdown(
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Result<(), Error>>
[src]Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down. Read more
fn poll_write_vectored(
self: Pin<&mut Self>,
cx: &mut Context<'_>,
bufs: &[IoSlice<'_>]
) -> Poll<Result<usize, Error>>
[src]
fn poll_write_vectored(
self: Pin<&mut Self>,
cx: &mut Context<'_>,
bufs: &[IoSlice<'_>]
) -> Poll<Result<usize, Error>>
[src]Like poll_write
, except that it writes from a slice of buffers. Read more
fn is_write_vectored(&self) -> bool
[src]
fn is_write_vectored(&self) -> bool
[src]Determines if this writer has an efficient poll_write_vectored
implementation. Read more
