SystemClock

Struct SystemClock 

Source
pub struct SystemClock;
Expand description

Real system clock (REQ-CLK-001/002). Zero-sized; Clock is implemented on a shared reference so one instance can be handed across threads.

With the ptp feature, quality() lazily runs detect_sync_quality once and caches it process-wide (G2: advisory, read at discovery time).

Implementations§

Source§

impl SystemClock

Source

pub const fn new() -> Self

Create the clock.

Trait Implementations§

Source§

impl Clock for SystemClock

Source§

fn now(&self) -> Timestamp

Current reading. t.mono never decreases across calls within a process, even if the underlying source regresses. REQ-CLK-001.
Source§

fn quality(&self) -> SyncQuality

Advisory sync quality of the underlying source (G2 — a hint, never a guarantee). REQ-CLK-004.
Source§

fn source(&self) -> ClockSource

Which underlying source reads are actually served from. REQ-CLK-003.
