pub struct Past<T>(/* private fields */)
where
T: Clone + Debug;
Expand description
Moves timeseries by length
items forward
It’s just a simple method-like wrapper for Window<T>
§Parameters
Has a single parameter length
: PeriodType
length
should be > 0
§Input type
Input type is any T: Copy + std::fmt::Debug
§Output type
Output type is the same as input type
§Examples
use yata::prelude::*;
use yata::methods::Past;
// Move of length=3
let mut past = Past::new(3, &1.0).unwrap();
past.next(&1.0);
past.next(&2.0);
past.next(&3.0);
assert_eq!(past.next(&4.0), 1.0);
assert_eq!(past.next(&5.0), 2.0);
assert_eq!(past.next(&6.0), 3.0);
§Performance
O(1)
