Struct Process

pub struct Process { /* private fields */ }

An async child process

Implementations

impl Process

pub fn try_recv(&mut self) -> Result<ProcessEvent, TryRecvError>

Try to receive an event from the child. This should be called after mio’s Poll returns an event for this token

pub fn kill(&mut self) -> Result<()>

Kill the process child, and all it’s children.

pub fn id(&self) -> u32

Returns the OS-assigned process identifier associated with this child.

Trait Implementations

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<()>

Deregister the child process with the poll

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_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

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

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

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

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

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

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

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
