Trait Implementations

impl Write for Process

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

Write a buffer to the Stdin stream of this child process.

If the child is not created with .stdin(Stdio::piped()), This function will return an error ErrorKind::NotConnected.

fn flush(&mut self) -> Result<()>

Flushed the Stdin stream of this child process.

If the child is not created with .stdin(Stdio::piped()), This function will return an error ErrorKind::NotConnected.

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

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.

impl Evented for Process

fn register(     &self,     poll: &Poll,     token: Token,     interest: Ready,     ops: PollOpt ) -> Result<()>

Register the child process with the poll so it can notify when the child process updates

fn reregister(     &self,     poll: &Poll,     token: Token,     interest: Ready,     ops: PollOpt ) -> Result<()>

Reregister the child process with the poll so it can notify when the child process updates

fn deregister(&self, poll: &Poll) -> Result<()>
