bsearch_index()
public
By using binary search, finds an index of a value from this array which meets the given condition in O(log n) where n is the size of the array.
It supports two modes, depending on the nature of the block and they are exactly the same as in the case of #bsearch method with the only difference being that this method returns the index of the element instead of the element itself. For more details consult the documentation for #bsearch.
