Struct VariableNoFlow

pub struct VariableNoFlow<T = f64> { /* private fields */ }

An axis with variable sized bins and no overflow bins.

An axis with variable sized bins constructed with a list of bin edges. This axis has (num edges - 1) bins.

For floating point types, infinities and NaN do not map to any bin.

Example

Create a 1D histogram with 3 variable width bins between 0.0 and 7.0.

   use ndhistogram::{ndhistogram, Histogram};
   use ndhistogram::axis::{Axis, VariableNoFlow};
   let mut hist = ndhistogram!(VariableNoFlow::new(vec![0.0, 1.0, 3.0, 7.0])?; i32);
   hist.fill(&-1.0); // will be ignored as there is no underflow bin
   hist.fill(&1.0);
   hist.fill(&2.0);
   assert_eq!(
       hist.values().copied().collect::<Vec<_>>(),
       vec![0, 2, 0],
   );

Implementations

impl<T: PartialOrd + Copy> VariableNoFlow<T>

pub fn new<I: IntoIterator<Item = T>>(bin_edges: I) -> Result<Self, AxisError>

Factory method to create an variable binning from a set of bin edges with no under/overflow bins. See the documentation for Variable::new.

The parameters must satify the same constraints as Variable::new, otherwise an error is returned.

pub fn low(&self) -> &T

Return the lowest bin edge.

pub fn high(&self) -> &T

Return the highest bin edge.

Trait Implementations

impl<T: PartialOrd + Copy> Axis for VariableNoFlow<T>

type Coordinate = T

The type representing a location on this axis.

type BinInterval = BinInterval<T>

The type of an interval representing the set of Coordinates that correspond to a histogram bin

fn index(&self, coordinate: &Self::Coordinate) -> Option<usize>

Map from coordinate to bin number. Returns an option as not all valid coordinates are necessarily contained within a bin.

fn num_bins(&self) -> usize

The number of bins in this axis, including underflow and overflow.

fn bin(&self, index: usize) -> Option<Self::BinInterval>

Map from bin number to axis to the interval covering the range of coordinates that this bin contains. Returns an option in case an index >= Axis::num_bins is given.

fn indices(&self) -> Box<dyn Iterator<Item = usize>>

An iterator over bin numbers

fn iter(&self) -> Box<dyn Iterator<Item = (usize, Self::BinInterval)> + '_>

An iterator over bin numbers and bin intervals

fn bins(&self) -> Box<dyn Iterator<Item = Self::BinInterval> + '_>

An iterator over bin intervals.

fn num_dim(&self) -> usize

The number of dimensions that this object corresponds to. For most Axis types this will simply be 1. However, Axes (i.e. a set of Axis) also implement Axis and should return the number of Axis that it contains.

impl<T: Clone> Clone for VariableNoFlow<T>

fn clone(&self) -> VariableNoFlow<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for VariableNoFlow<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for VariableNoFlow<T>

fn default() -> VariableNoFlow<T>

Returns the “default value” for a type.

impl<T: PartialOrd + Copy + Display> Display for VariableNoFlow<T>

where Self: Axis,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Hash> Hash for VariableNoFlow<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, T: PartialOrd + Copy> IntoIterator for &'a VariableNoFlow<T>

type Item = (usize, <VariableNoFlow<T> as Axis>::BinInterval)

The type of the elements being iterated over.

type IntoIter = Box<dyn Iterator<Item = <&'a VariableNoFlow<T> as IntoIterator>::Item> + 'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: Ord> Ord for VariableNoFlow<T>

fn cmp(&self, other: &VariableNoFlow<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for VariableNoFlow<T>

fn eq(&self, other: &VariableNoFlow<T>) -> 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.

impl<T: PartialOrd> PartialOrd for VariableNoFlow<T>

fn partial_cmp(&self, other: &VariableNoFlow<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
