Struct DaemonNotifier 

Source 
pub struct DaemonNotifier { /* private fields */ }
Expand description

Startup token held by the detached daemon until initialization finishes.

Implementations§

Source§

impl DaemonNotifier

Source

pub const fn process(&self) -> DaemonProcess

Return this daemon’s process and group handles.

Source

pub fn notify_ready(self) -> Result<()>

Report successful initialization to the original invoker.

§Errors

Returns the startup-pipe write error, normally EPIPE when the invoker has already timed out or exited.

Source

pub fn fail_and_exit(self, error: &Error) -> !

Report initialization failure and terminate the detached daemon.

The explicit name reflects that this method never returns and uses _exit so inherited application destructors are not run.
