Struct reparser::def::io::Stderr 1.0.0[−][src]
pub struct Stderr { /* fields omitted */ }
Expand description
A handle to the standard error stream of a process.
For more information, see the io::stderr
method.
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.
Implementations

[src]pub fn lock(&self) -> StderrLock<'_>ⓘNotable traits for StderrLock<'_>

[src]
pub fn lock(&self) -> StderrLock<'_>ⓘNotable traits for StderrLock<'_>
impl<'_> Write for StderrLock<'_>
[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_all(b"hello world")?; Ok(()) }
