Struct stm32f407g_disc::dwt::StopWatch [−][src]
pub struct StopWatch<'l> { /* fields omitted */ }Very simple stopwatch which reads from DWT Cycle Counter to record timing.
Since DWT Cycle Counter is a 32-bit counter that wraps around to 0 on overflow,
users should be aware that StopWatch cannot correctly measure laps
which take longer than u32::MAX cycles
Implementations
impl<'l> StopWatch<'l>[src]
pub fn lap_count(&self) -> usize[src]
Returns the numbers of laps recorded
pub fn reset(&mut self)[src]
Resets recorded laps to 0 and sets 0 offset
pub fn lap(&mut self) -> &mut StopWatch<'l>[src]
Record a new lap.
If lap count exceeds maximum, the last lap is updated
pub fn lap_time(&self, n: usize) -> Option<ClockDuration>[src]
Calculate the time of lap n (n starting with 1).
Returns None if n is out of range
