Struct ManualClock 

pub struct ManualClock(/* private fields */);

A clock whose reading is whatever the caller last set.

This is not a simulator and must not grow into one by accident: it does not advance itself, it has no notion of a pending timer, and nothing schedules against it. It exists so that a test can assert a program’s behaviour at a stated instant, and so that the seam has a second implementation — a seam with one implementation is an abstraction nobody has checked.

Implementations

impl ManualClock

pub fn at(millis: i64) -> ManualClock

pub fn set(&self, millis: i64)

pub fn advance(&self, millis: i64)

Move the clock forward. Panics on a negative step, because a wall clock that goes backwards is a bug in the test rather than a scenario worth supporting.

Trait Implementations

impl Clock for ManualClock

fn now_millis(&self) -> i64

Milliseconds since the Unix epoch.

fn now_nanos(&self) -> u64

Nanoseconds since the Unix epoch — the unit OTLP asks for.

impl Debug for ManualClock

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

Formats the value using the given formatter.
