Struct tokio_process::ChildStdin

pub struct ChildStdin { /* fields omitted */ }

The standard input stream for spawned children.

This type implements the Write trait to pass data to the stdin handle of a child process. Note that this type is also "futures aware" meaning that it is both (a) nonblocking and (b) will panic if used off of a future's task.

Trait Implementations

impl AsRawHandle for ChildStdin

fn as_raw_handle(&self) -> RawHandle

Extracts the raw handle, without taking any ownership.

impl AsyncWrite for ChildStdin

fn shutdown(&mut self) -> Poll<(), Error>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

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

Attempt to write bytes from buf into the object.

fn poll_flush(&mut self) -> Result<Async<()>, Error>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn write_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where
    B: Buf, 

Write a Buf into this value, returning how many bytes were written.

impl Debug for ChildStdin

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

Formats the value using the given formatter.

impl Write for ChildStdin

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

Write a buffer into this writer, 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_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

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

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

Attempts to write an entire buffer into this writer.

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.
