Struct shared_child::SharedChild

pub struct SharedChild { /* fields omitted */ }

Implementations

impl SharedChild

pub fn spawn(command: &mut Command) -> Result<SharedChild>

Spawn a new SharedChild from a std::process::Command.

pub fn id(&self) -> u32

Return the child process ID.

pub fn wait(&self) -> Result<ExitStatus>

Wait for the child to exit, blocking the current thread, and return its exit status.

pub fn try_wait(&self) -> Result<Option<ExitStatus>>

Return the child’s exit status if it has already exited. If the child is still running, return Ok(None).

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

Send a kill signal to the child. On Unix this sends SIGKILL, and you should call wait afterwards to avoid leaving a zombie. If the process has already been waited on, this returns Ok(()) and does nothing.

pub fn into_inner(self) -> Child

Consume the SharedChild and return the std::process::Child it contains.

We never reap the child process except through Child::wait, so the child object’s inner state is correct, even if it was waited on while it was shared.

impl SharedChildExt for SharedChild

fn send_signal(&self, signal: c_int) -> Result<()>
