Struct hanower::Interval

pub struct Interval { /* fields omitted */ }

Used to create and work with intervals which are calculated from the user-input CLI values.

• low is the starting point of the section from which to find intervals
• high is the inclusive end point of the section from which to find intervals
• count is the total number of desired intervals to be calculated
  • must be a minimum of 1 (prints interval of low to high)

Note: values are rounded to 12 significant decimal places.

Implementations

impl Interval

pub fn new(low: f64, high: f64, count: u64) -> Result<Self, IntervalError>

Creates a new Interval, with the range low..=high, split into count number of intervals.

pub fn low(&self) -> f64

Returns the low value.

pub fn high(&self) -> f64

Returns the high value.

pub fn count(&self) -> u64

Returns the count value.

pub fn bucket(&self, number: f64) -> Option<usize>

Finds the bucket a given value exists in.

A bucket refers to a range between two values, and including the starting value (similar to an interval).

For example, say we have values of low = 1, high = 10, and count = 5, and want to know which bucket the number 8 would be in. The output intervals would be 1 2 3 4 6 10. The first bucket is then 2..<3, next 3..<4, etc. So, 8 is in the fourth bucket, between 6 and 10.

pub fn iter(&self) -> IntervalIter

Returns an iterator of lazily evaluated intervals, starting from this Interval’s low value up to and including the high value.

pub fn intervals(&self) -> IntervalIter

Returns an iterator of lazily evaluated intervals based on the low and high points of this Interval.

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Interval

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.
