Implementations

impl Profiler

pub fn new() -> Self

fn update_slow_event( &mut self, dst_counter: usize, counters: &[usize], threshold: f64 )

Sum a few counters and if the total amount is larger than a threshold, update a specific counter.

This is useful to monitor slow frame and slow transactions.
