Expand description

Implements histogram

  • anything that implements Histogram should also implement the trait HistogramVal

Required Methods§

source

fn count_multiple_index( &self, index: usize, count: usize ) -> Result<(), HistErrors>

self.hist[index] += count, Err() if index out of bounds
source

fn hist(&self) -> &[AtomicUsize]

the created histogram

Since this uses atomics, you can also write to the underlying hist yourself, if you so desire

source

fn reset(&mut self)

reset the histogram to zero

Provided Methods§

source

fn count_index(&self, index: usize) -> Result<(), HistErrors>

self.hist[index] += 1, Err() if index out of bounds
source

fn bin_count(&self) -> usize

How many bins the histogram contains
source

fn any_bin_zero(&self) -> bool

check if any bin was not hit yet
  • Uses SeqCst Ordering
