Struct std::io::Stderr

pub struct Stderr { /* fields omitted */ }

A handle to the standard error stream of a process.

For more information, see the io::stderr method.

Methods

impl Stderr [src]

[src]

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 std::io::{self, Write};

fn foo() -> io::Result<()> {
    let stderr = io::stderr();
    let mut handle = stderr.lock();

    handle.write(b"hello world")?;

    Ok(())
}
