Struct ClockTimer

pub struct ClockTimer { /* private fields */ }

The ClockTimer type is a wrapper class for platform-specific clocks. It can be used for cycle counters and execution time clocks, for example.

Implementations

impl ClockTimer

pub fn new(clock: Rc<RefCell<dyn SimpleClock>>) -> ClockTimer

pub fn new_box(clock: Rc<RefCell<dyn SimpleClock>>) -> TimerBox

Trait Implementations

impl Clone for ClockTimer

fn clone(&self) -> ClockTimer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Timer for ClockTimer

fn start(&mut self)

The start() method starts a timing interval. It may be called multiple times on a single instance. The last invocation of the start method overrides any previous calls.

fn finish(&mut self) -> i64

The finish() method is used at the end of a sample interval. It returns the interval time in ticks and also starts a new interval, since the restart cost is nearly zero. Thus, finish() can be called multiple times after a start() invocation to return the times for a sequence of events. If a more precise timing is required, the user must invoke start().

fn hz(&self) -> u128

hz() returns the frequency of the underlying clock.
