Struct Window 

pub struct Window<P: AxisProfile> { /* private fields */ }

A sliding window over a monoid: the fold of the last capacity pushed values, in push order, with each value folded at most twice.

back holds the newer values with back_fold their running fold; front holds suffix folds of the older values, oldest last, so the oldest value’s entry is the fold of everything in front. When front runs out the whole of back moves across as suffix folds. The window’s fold is front.last() ⊕ back_fold.

Implementations

impl<P: AxisProfile> Window<P>

pub fn new(capacity: usize) -> Self

pub fn len(&self) -> usize

Values in the window.

pub fn is_empty(&self) -> bool

Whether the window holds nothing.

pub fn push(&mut self, value: P)

Push the newest value, dropping the oldest when the window is full.

pub fn fold(&self) -> P
