Implementations§

Source§

impl Child

Source

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)
42async fn rebuild(cx: Context, builds: Rc<Cell<u32>>, running: Rc<Cell<bool>>) {
43    publish(&cx, "building", builds.get());
44    let passed = process::spawn("make", &[], None)
45        .and_then(|child| child.wait())
46        .is_ok_and(|status| status == 0);
47    builds.set(builds.get() + 1);
48    running.set(false);
49    publish(&cx, if passed { "passed" } else { "failed" }, builds.get());
50}
Source

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

The exit status once the program exited.

Source

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

Writes to a Stdio::Piped stdin.

Source

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

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

Source

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

Kills the program’s process group.
