Struct Child 

pub struct Child {
    pub pid: u32,
}

A spawned program.

Fields

pid: u32

Implementations

impl Child

pub fn wait(self) -> Result<i32>

Blocks the plugin until the program exits; its exit status (a signal is negated). Prefer awaiting Event::ProcessExited.

Examples found in repository

examples/together_companion.rs (line 45)

async fn rebuild(cx: Context, builds: Rc<Cell<u32>>, running: Rc<Cell<bool>>) {
    publish(&cx, "building", builds.get());
    let passed = process::spawn("make", &[], None)
        .and_then(|child| child.wait())
        .is_ok_and(|status| status == 0);
    builds.set(builds.get() + 1);
    running.set(false);
    publish(&cx, if passed { "passed" } else { "failed" }, builds.get());
}

pub fn wait_timeout(self, timeout: Duration) -> Result<Option<i32>>

Blocks the plugin until the program exits or timeout passes: its exit status, or none when it still runs (kill it then).

pub fn try_wait(self) -> Result<Option<i32>>

The exit status once the program exited.

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

Writes to a Stdio::Piped stdin.

pub fn close_stdin(self) -> Result<()>

Closes a piped stdin: the program reads end of file.

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

Kills the program’s process group.
