Struct RobotClock 

pub struct RobotClock { /* private fields */ }

A running Robot clock. The clock is a monotonic clock that starts at an arbitrary reference time. It is clone resilient, ie a clone will be the same clock, even when mocked.

Implementations

impl RobotClock

pub fn new() -> RobotClock

Creates a RobotClock using now as its reference time. It will start at 0ns incrementing monotonically. This uses the std System Time as a reference clock.

pub fn new_with_rtc( read_rtc_ns: impl Fn() -> u64 + Send + Sync + 'static, sleep_ns: impl Fn(u64) + Send + Sync + 'static, ) -> RobotClock

Builds a RobotClock using a reference RTC clock to calibrate with. This is mandatory to use with the no-std platforms as we have no idea where to find a reference clock.

pub fn from_ref_time(ref_time_ns: u64) -> RobotClock

Builds a monotonic clock starting at the given reference time.

pub fn from_ref_time_with_rtc( read_rtc_ns: fn() -> u64, sleep_ns: fn(u64), ref_time_ns: u64, ) -> RobotClock

Overrides the RTC with a custom implementation, should be the same as the new_with_rtc.

pub fn mock() -> (RobotClock, RobotClockMock)

Build a fake clock with a reference time of 0. The RobotMock interface enables you to control all the clones of the clock given.

pub fn now(&self) -> CuDuration

Now returns the time that passed since the reference time, usually the start time. It is a monotonically increasing value.

pub fn recent(&self) -> CuDuration

A less precise but quicker time

Trait Implementations

impl Clone for RobotClock

fn clone(&self) -> RobotClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RobotClock

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

Formats the value using the given formatter.

impl Default for RobotClock

We cannot build a default RobotClock on no-std because we don’t know how to find a reference clock. Use RobotClock::new_with_rtc instead on no-std.

fn default() -> RobotClock

Returns the “default value” for a type.
