Struct std::io::Stderr

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

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.

Trait Implementations

impl Write for Stderr

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, args: Arguments) -> Result<()>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self where Self: Sized

Creates a "by reference" adaptor for this instance of Write.
