$ npm i @x-oasis/integer-buffer-setimport IntegerBufferSet from '@x-oasis/integer-buffer-set'$ pnpm testBasically, we only compare index value, such as
create a onTheFlyIndices as a slave buffer. theoretically, at most buffer size's new
item could occupy a position.
IndexExtractor is the key point of design.
if you do not delete/reorder an an array, indexExtractor is useless.
when getIndices..
positionToMetaIndices may used as a supplement. but when has multiple buffer. index refer to meta may changed to other buffer..
const data = [0, 1, 2, 3, 4, 5] only reuse m % 3 === 0, but when an item is deleted..
all these index after delete index value will be invalid, because m % 2 === 0 could not be reused.
