Struct StdClock 

pub struct StdClock { /* private fields */ }

Clock backed by the operating system’s clocks.

Monotonic time is measured from an Instant epoch captured when the clock is created, so monotonic_ms starts near zero and cannot go backwards. Wall-clock time comes from SystemTime and can jump in either direction as the system clock is adjusted, which is exactly why the two are reported separately; a system clock set before the Unix epoch reports no wall-clock time at all rather than a nonsense timestamp.

Example

use minip2p_platform::{Clock, StdClock};

let mut clock = StdClock::new();
let start = clock.now();
let later = clock.now();
assert!(later.monotonic_ms >= start.monotonic_ms);

Implementations

impl StdClock

pub fn new() -> Self

Creates a clock whose monotonic timeline starts now.

pub fn with_epoch(epoch: Instant) -> Self

Creates a clock measuring monotonic time from an existing epoch.

Use this to keep several clocks on one timeline, so their samples stay comparable.

pub fn epoch(&self) -> Instant

Returns the epoch this clock measures monotonic time from.
