Struct SpawnedChild 

pub struct SpawnedChild {
    pub stdin: Option<ChildStdin>,
    pub stdout: Option<ChildStdout>,
    pub stderr: Option<ChildStderr>,
    /* private fields */
}

Handle to a contained child spawned via spawn.

On Drop, SpawnedChild synchronously kills the child:

• Windows: closes the Job Object handle; KILL_ON_JOB_CLOSE causes the kernel to terminate every process in the job (the child and its descendants).
• Unix: killpg(pgid, SIGKILL) and waitpid to reap.

The optional stdin / stdout / stderr fields are present when the corresponding StdioSource was StdioSource::Pipe; otherwise they are None.

Fields

stdin: Option<ChildStdin>

stdout: Option<ChildStdout>

stderr: Option<ChildStderr>

Implementations

impl SpawnedChild

pub fn id(&self) -> u32

Process ID of the spawned child.

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

Forcibly terminate the child. Best-effort.

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

Block until the child exits and return its exit code.

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

Non-blocking variant of Self::wait.

Trait Implementations

impl Drop for SpawnedChild

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
