Struct sgx_tstd::io::Stderr

pub struct Stderr { /* fields omitted */ }

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.

Methods

impl Stderr

pub 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 AsRawFd for Stderr

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Debug for Stderr

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Write for Stderr

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

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

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize>

Like write, except that it writes from a slice of buffers.

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 writer.

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

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

fn write_all_vectored(&mut self, bufs: &mut [IoSlice]) -> Result<()>

Attempts to write multiple buffers into this writer.

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

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