Module Base.Binary_searchable_intf

Module types for a binary_search function for a sequence, and functors for building binary_search functions.

module type Indexable : sig ... end

An Indexable type is a finite sequence of elements indexed by consecutive integers 0 ... length t - 1. get and length must be O(1) for the resulting binary_search to be lg(n).
