pub struct Stderr { /* fields omitted */ }
A handle to the standard error stream of a process.
For more information, see the io::stderr
method.
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.
use std::io::{self, Write};
fn foo() -> io::Result<()> {
let stderr = io::stderr();
let mut handle = stderr.lock();
handle.write(b"hello world")?;
Ok(())
