Struct SupervisedChild 

pub struct SupervisedChild { /* private fields */ }

Running child process owned by the supervisor.

Implementations

impl SupervisedChild

pub fn program(&self) -> &str

Program path or name used to spawn the child.

pub fn id(&self) -> Option<u32>

Operating-system process id, if the child has started and is still known.

pub fn take_stdin(&mut self) -> Option<ChildStdin>

Take the child’s stdin pipe.

pub fn take_stdout(&mut self) -> Option<ChildStdout>

Take the child’s stdout pipe.

pub fn take_stderr(&mut self) -> Option<ChildStderr>

Take the child’s stderr pipe.

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

Return the child exit status if it has already exited.

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

Wait for the child to exit.

pub async fn kill_and_wait(&mut self) -> Result<ExitStatus, NodeSupervisorError>

Force-stop the child process itself and wait for it to exit.

This kills only the direct child; use the process-group shutdown path when the child may have spawned its own descendants.

pub fn terminate_process_group(&self) -> Result<(), NodeSupervisorError>

Send SIGTERM to the child’s process group.

pub fn kill_process_group(&self) -> Result<(), NodeSupervisorError>

Send SIGKILL to the child’s process group.

pub fn process_group_exists(&self) -> Result<bool, NodeSupervisorError>

Return true when the child’s process group still has live members.

Trait Implementations

impl Debug for SupervisedChild

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SupervisedChild

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.
