pub struct AveragedCollection<T: ToPrimitive + Copy> { /* private fields */ }

A collection that retains an average value of its elements

Implementations

impl<T> AveragedCollection<T>

where T: ToPrimitive + Copy,

pub fn new() -> AveragedCollection<T>

adds a new element and updates the average

Example

use averaged_collection::AveragedCollection;
let mut avg_collection = AveragedCollection::new();
avg_collection.add(1);
avg_collection.add(2);
assert_eq!(avg_collection.average(), 1.5);

use averaged_collection::AveragedCollection;
use assert_approx_eq::assert_approx_eq;
let mut avg_collection = AveragedCollection::new();
avg_collection.add(1.2);
avg_collection.add(1.4);
avg_collection.add(1.6);
assert_approx_eq!(avg_collection.average(), 1.4);
