[][src]Struct async_std::io::Stderr

pub struct Stderr(_);

A handle to the standard error of the current process.

This writer is created by the stderr function. See its documentation for more.

Note: Windows Portability Consideration

When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.

Methods

impl Stderr[src]

pub async fn lock<'_>(&'_ self) -> StderrLock<'static>[src]

This is supported on unstable only.

Locks this handle to the standard error stream, returning a writable guard.

The lock is released when the returned lock goes out of scope. The returned guard also implements the Write trait for writing data.

Examples

use async_std::io;
use async_std::prelude::*;

let stderr = io::stderr();
let mut handle = stderr.lock().await;

handle.write_all(b"hello world").await?;
