6. class SegmentReadState extends SegmentReadStateOption

   

   Both Get and Higher functions mutate foundKeyValue.

   Both Get and Higher functions mutate foundKeyValue. But lower can only mutate foundLowerKeyValue as it depends on get to fetch the end key-value for faster lower search and should not mutate get's set foundKeyValue.
