Data.HdrHistogram.Config
Contents
Description
A Haskell implementation of HdrHistogram. It allows storing counts of observed values within a range, while maintaining precision to a configurable number of significant digits.
This module captures the common functionality of converting values to
and from Int indices, regardless of mutability or memory layout.
- data Config lowest highest sig
- type HighLow a b = a <= (b - 1)
- type SigBounds sig = (1 <= sig, sig <= 5)
- class HasConfig s where
- size :: HistogramConfig a -> Int
- indexForValue :: (FiniteBits a, Integral a) => HistogramConfig a -> a -> Int
- data Range a = Range {}
- rangeForIndex :: (Integral a, Bits a) => HistogramConfig a -> Int -> Range a
