Struct SpawnedChild 

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

Handle and optional parent pipe ends for a contained child.

Dropping this value shuts down the contained process group.

Fields

stdin: Option<ChildStdin>

Writable parent end when standard input was configured as a pipe.

stdout: Option<ChildStdout>

Readable parent end when standard output was configured as a pipe.

stderr: Option<ChildStderr>

Readable parent end when standard error was configured as a pipe.

Implementations

impl SpawnedChild

pub fn id(&self) -> u32

Return the operating-system process identifier.

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

Forcibly terminate the child on a best-effort basis.

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

Wait for the child and return its numeric exit code.

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

Return the exit code if the child has finished without blocking.

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.
