Struct std::io::StderrLock

pub struct StderrLock<'a> { /* fields omitted */ }

A locked reference to the Stderr handle.

This handle implements the Write trait and is constructed via the Stderr::lock method.

Trait Implementations

impl<'a> Write for StderrLock<'a>

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, fmt: Arguments) -> Result<()>

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