Trait embedded_profiling::EmbeddedProfiler

}

The main trait to implement. All that is required is a way to read time and a way to output our results, if desired. You can also implement functions that get called when a snapshot starts and ends.

Required methods

fn read_clock(&self) -> EPInstant

Takes a reading from the clock

Provided methods

fn log_snapshot(&self, _snapshot: &EPSnapshot)

Optionally log the snapshot to some output, like a serial port

fn at_start(&self)

Optional function that gets called at the start of the snapshot recording. If one would want to very simple profiling, they could use at_start and at_end to simply toggle a GPIO.

fn at_end(&self)

Optional function that gets called at the end of the snapshot recording

fn start_snapshot(&self) -> EPInstant

takes the starting snapshot of a specific trace

fn end_snapshot(
    &self,
    start: EPInstant,
    name: &'static str
) -> Option<EPSnapshot>

computes the duration of the snapshot given the start time, if there hasn’t been overflow
