interface CachedIterator

import { type CachedIterator } from "https://deno.land/x/iterators@v0.2.0/mod.ts";

CachedIterator is an iterator that stores previous generated values.

Type Parameters

optional

TReturn = any

optional

TNext = undefined

[[Symbol.iterator]](): this

next(...args: [] | [TNext]): Readonly<IteratorResult<T, TReturn>>

next() moves the iterator forwards one step and calculates the value if it is not cached.

prev(): Readonly<IndexedIteratorResult<T, TReturn>>

prev() moves the iterator back one step.

If there is nothing in the cache (ie. next() hasn't been called), prev() will throw.
