Struct os_pipe::PipeWriter

pub struct PipeWriter(_);

The writing end of a pipe, returned by pipe.

PipeWriter implements Into<Stdio>, so you can pass it as an argument to Command::stdout or Command::stderr to spawn a child process that writes to the pipe.

Methods

impl PipeWriter

pub fn try_clone(&self) -> Result<PipeWriter>

Trait Implementations

impl IntoRawHandle for PipeWriter

fn into_raw_handle(self) -> RawHandle

Consumes this object, returning the raw underlying handle.

impl AsRawHandle for PipeWriter

fn as_raw_handle(&self) -> RawHandle

Extracts the raw handle, without taking any ownership.

impl FromRawHandle for PipeWriter

Important traits for PipeWriter

impl Write for PipeWriterimpl<'a> Write for &'a PipeWriter

unsafe fn from_raw_handle(handle: RawHandle) -> PipeWriter

Constructs a new I/O object from the specified raw handle.

impl Debug for PipeWriter

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

Formats the value using the given formatter.

impl Write for PipeWriter

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.

Attempts to write an entire buffer into this write.

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

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

fn by_ref(&mut self) -> &mut Self

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