Struct std::io::Stderr1.0.0 [] [src]

pub struct Stderr {
    // some fields omitted
}

A handle to the standard error stream of a process.

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

Methods

impl Stderr
[src]

fn lock(&self) -> StderrLock

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

fn main() { use std::io::{self, Write}; fn foo() -> io::Result<()> { let stderr = io::stderr(); let mut handle = stderr.lock(); try!(handle.write(b"hello world")); Ok(()) } }
use std::io::{self, Write};

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

    try!(handle.write(b"hello world"));

    Ok(())
}
