Struct average::Histogram10

pub struct Histogram10 { /* fields omitted */ }

A histogram with a number of bins known at compile time.

Methods

impl Histogram

pub fn with_const_width(start: f64, end: f64) -> Self

Construct a histogram with constant bin width.

pub fn from_ranges<T>(ranges: T) -> Result<Self, ()> where
    T: IntoIterator<Item = f64>, 

Construct a histogram from given ranges.

The ranges are given by an iterator of floats where neighboring pairs (a, b) define a bin for all x where a <= x < b.

Fails if the iterator is too short (less than n + 1 where n is the number of bins), is not sorted or contains nan. inf and empty ranges are allowed.

pub fn find(&self, x: f64) -> Result<usize, ()>

Find the index of the bin corresponding to the given sample.

Fails if the sample is out of range of the histogram.

pub fn add(&mut self, x: f64) -> Result<(), ()>

Add a sample to the histogram.

Fails if the sample is out of range of the histogram.

pub fn ranges(&self) -> &[f64]

Return the ranges of the histogram.

pub fn iter(&self) -> IterHistogram

Return an iterator over the bins and corresponding ranges: ((lower, upper), count)

pub fn reset(&mut self)

Reset all bins to zero.

pub fn range_min(&self) -> f64

Return the lower range limit.

(The corresponding bin might be empty.)

pub fn range_max(&self) -> f64

Return the upper range limit.

(The corresponding bin might be empty.)
