Module type Hashtbl.HashedType

module type HashedType : sig ... end
The input signature of the functor Hashtbl.Make. t is the type of keys. equal is the equality predicate used to compare keys. hash is a hashing function on keys, returning a non-negative integer. It must be such that if two keys are equal according to equal, then they must have identical hash values as computed by hash. Examples: suitable (equal, hash) pairs for arbitrary key types include ((=), Hashtbl.hash) for comparing objects by structure, and ((==), Hashtbl.hash) for comparing objects by addresses (e.g. for mutable or cyclic keys).
