Struct winvec::WinVec

pub struct WinVec<T>(_, _);

Windowed Vector

A Collection that purges keys based on a fixed TTL.

Useful for rolling windows and other time based collections/caches.

We purge old keys on read, rather than on insert. You can specify the duration via with_duration(). Add elements with push or push_with_timestamp. View elements via iter and into_iter

Implementations

impl<'a, T> WinVec<T>

pub fn with_duration(dur: Duration) -> Self

Create a new Windowed Vector with a set duration

pub fn push(&mut self, el: T)

Push an element into the windowed array

pub fn push_with_timestamp(&mut self, el: T, instant: Instant)

Push an element with a specified timestamp

pub fn from_vec(vec: Vec<T>, dur: Duration) -> Self

pub fn duration(&self) -> Duration

impl<'a, T: Clone> WinVec<T>

pub fn len(&mut self) -> usize

Returns the number of elements within the collection. We purge and then return the new length.

pub fn iter(&'a mut self) -> impl 'a + Iterator<Item = T>

Purges & Returns an Interator of the elements

Trait Implementations

impl<T: Clone> Clone for WinVec<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Clone> IntoIterator for WinVec<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
