Custom Collections (Scala 2.13): forcing laziness in infinite lists

[hmf]

@Jasper-M

If you need an Iterator that can be reused you can do View.from(iterator) .

Indeed this is what I am looking for. I don’t know how views work, but one possible disadvantage is loosing the ability to create a collection and reuse all underlying methods. Going to look at this.

As a side note, after some more search I found that I already had asked a similar question. There, one of the collection gurus had said:

@szeiger

override the iterableFactory to build a lazy collection

which, (as seen in the code above) still seems problematic because I have only access to an IterableOnce.

@Jasper-M

If you want the already calculated elements to be memoized use LazyList .

I meant lazy in the sense of processing the sequence. Maybe their is a better word for this?

Thanks
