Struct std::io::Stderr 1.0.0[−][src]
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]
impl StderrⓘImportant traits for StderrLock<'a>pub fn lock(&self) -> StderrLock[src]
pub fn lock(&self) -> StderrLockLocks 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(()) }Run
