Enum NotifyState

pub enum NotifyState<'a> {
    Ready,
    Reloading,
    Stopping,
    Status(&'a str),
    Errno(u32),
    BusError(&'a str),
    MainPid(u32),
    Watchdog,

    WatchdogUsec(u32),
    ExtendTimeoutUsec(u32),
    MonotonicUsec(i128),
    Custom(&'a str),
}

Daemon notification for the service manager.

Variants

Ready

Service startup is finished.

Reloading

Service is reloading its configuration.

On systemd v253 and newer, this message MUST be followed by a NotifyState::MonotonicUsec notification, or the reload will fail and the service will be terminated.

Stopping

Service is stopping.

Status(&'a str)

Free-form status message for the service manager.

Errno(u32)

Service has failed with an errno-style error code, e.g. 2 for ENOENT.

BusError(&'a str)

Service has failed with a D-Bus-style error code, e.g. org.freedesktop.DBus.Error.TimedOut.

MainPid(u32)

Main process ID (PID) of the service, in case it wasn’t started directly by the service manager.

Watchdog

Tells the service manager to update the watchdog timestamp.

WatchdogTrigger

Tells the service manager to trigger a watchdog failure.

WatchdogUsec(u32)

Resets the configured watchdog value.

ExtendTimeoutUsec(u32)

Tells the service manager to extend the service timeout.

MonotonicUsec(i128)

Notify systemd of the current monotonic time in microseconds. You can construct this value by calling NotifyState::monotonic_usec_now().

Custom(&'a str)

Custom state.

Implementations

impl NotifyState<'_>

pub fn monotonic_usec_now() -> Result<Self>

Create a new NotifyState::MonotonicUsec using the current system monotonic time.

Example

let _ = NotifyState::monotonic_usec_now().expect("Failed to read monotonic time");

Trait Implementations

impl<'a> Clone for NotifyState<'a>

fn clone(&self) -> NotifyState<'a>

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for NotifyState<'a>

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

Formats the value using the given formatter.

impl Display for NotifyState<'_>

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