Struct BasicClock 

pub struct BasicClock {
    simulator_elapsed: Duration,
    wall_clock_time_origin: SystemTime,
}

BasicClock provides a simulated clock.

Examples

use std::time::Duration;
use cpu::BasicClock;
use cpu::Clock;
let mut clk = BasicClock::new();
clk.consume(&Duration::from_micros(12));

Fields

simulator_elapsed: Duration

Elapsed time as measured by the simulated clock.

wall_clock_time_origin: SystemTime

Origin time for the simulated RTC. When the SystemTime implementation appears to have advanced non-monotonically, we update wall_clock_time_origin.

Implementations

impl BasicClock

pub fn new() -> BasicClock

pub fn advance_to_simulated_time(&mut self, when: Duration)

pub fn make_fresh_context(&mut self) -> Context

Trait Implementations

impl Clock for BasicClock

fn now(&self) -> Duration

Retrieves the current (simulated) time.

fn consume(&mut self, interval: &Duration)

The caller calls consume to simulate the passing of a duration interval. The returned value is the interval after which it is next OK to call consume.

impl Debug for BasicClock

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

Formats the value using the given formatter.

impl Default for BasicClock

fn default() -> Self

Returns the “default value” for a type.
