Struct HistogramPoints 

pub struct HistogramPoints(/* private fields */);

A set of histogram points.

Used to represent the data points of histograms. Each data point is attached to an optional timestamp.

Histograms are conceptually similar to sketches, but hold all raw samples directly and thus have a slightly worse memory efficiency as the number of samples grows.

Implementations

impl HistogramPoints

pub fn is_empty(&self) -> bool

Returns true if this set is empty.

pub fn len(&self) -> usize

Returns the number of points in this set.

pub fn merge(&mut self, other: Self)

Merges another set of points into this one.

If a point with the same timestamp exists in both sets, the histograms will be merged together. Otherwise, the points will appended to the end of the set.

impl<'a> IntoIterator for &'a HistogramPoints

type Item = (Option<NonZero<u64>>, &'a Histogram)

The type of the elements being iterated over.

type IntoIter = HistogramIterRef<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a mut HistogramPoints

type Item = (Option<NonZero<u64>>, &'a mut Histogram)

The type of the elements being iterated over.

type IntoIter = HistogramIterRefMut<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for HistogramPoints

type Item = (Option<NonZero<u64>>, Histogram)

The type of the elements being iterated over.

type IntoIter = HistogramIter

impl PartialEq for HistogramPoints

fn eq(&self, other: &HistogramPoints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
