Struct sgx_tstd::io::Stdout

pub struct Stdout { /* fields omitted */ }

A handle to the global standard output stream of the current process.

Each handle shares a global buffer of data to be written to the standard output stream. Access is also synchronized via a lock and explicit control over locking is available via the lock method.

Created by the io::stdout 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 Stdout

pub fn lock(&self) -> StdoutLock

Locks this handle to the standard output 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 Stdout

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl Debug for Stdout

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

Formats the value using the given formatter.

impl Write for Stdout

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.
