Struct ProcessTree 

pub struct ProcessTree { /* private fields */ }

One child and descendants that remain in its operating-system containment.

Windows uses a Job object. Unix uses a process group, which cannot contain a descendant that deliberately creates a new process group or session.

Implementations

impl ProcessTree

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

Polls the direct child without releasing ownership of its descendants.

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

Waits for the direct child while retaining ownership of its descendants.

pub fn wait_with_output(&mut self) -> Result<Output>

Collects the direct child’s output while retaining the descendant guard.

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

Terminates every process in the tree and reaps the direct child.

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

Signals termination to the entire tree while retaining the direct child so its captured output can still be collected.

Trait Implementations

impl Drop for ProcessTree

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.
