Struct Clock 

pub struct Clock { /* private fields */ }

Monotonic clock anchored to an observer-startup baseline.

Mirrors the semantics of Observer::start.elapsed().as_nanos() so downstream stall arithmetic is unchanged when the operator does not pass --clock-source.

Implementations

impl Clock

pub fn new(source: ClockSource) -> Result<Self, ClockError>

Build a Clock backed by source.

Performs one clock_gettime(2) call to anchor start_ns. Returns ClockError::Unsupported when source = Boottime on a non-Linux target.

pub fn probe(source: ClockSource) -> Result<(), ClockError>

One-call probe: surface Unsupported / OS errors at startup before threading the clock through Observer.

pub fn now_ns(&self) -> u64

Nanoseconds since this Clock’s baseline. Saturates to u64::MAX on a wildly long-running process (>584 years).

pub fn source(&self) -> ClockSource

Inspect the configured source (used by tests and by main.rs to publish into the watchdog atomic).
