Struct tokio::io::Stderr

pub struct Stderr { /* fields omitted */ }

This is supported on feature="io-std" only.

A handle to the standard error stream of a process.

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

Created by the stderr function.

Trait Implementations

impl AsyncWrite for Stderr

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<(), Error>>

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

fn poll_shutdown(
    self: Pin<&mut Self>,
    cx: &mut Context
) -> Poll<Result<(), Error>>

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

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

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

impl Debug for Stderr

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

Formats the value using the given formatter.
