Struct DaemonChild 

pub struct DaemonChild { /* private fields */ }

Handle to a detached daemon spawned via spawn_daemon.

The daemon child always has stdin/stdout/stderr connected to the platform null device (NUL on Windows, /dev/null on Unix) — a detached process with inherited stdio is the classic crash-on-first- println! failure mode after the parent closes its end, so the daemon-spawn path forecloses that by construction. Dropping DaemonChild does NOT terminate the daemon; it only closes the OS handle the wrapper held. Call DaemonChild::kill to terminate.

Implementations

impl DaemonChild

pub fn id(&self) -> u32

Process ID.

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.
