`make-vector-comparator``element-comparator``type-test``length``ref`procedureThis procedure returns comparators whose functions behave as follows:

- The type test returns
`#t`if its argument satisfies`type-test`and the elements satisfy the type test predicate of`element-comparator`. - The equality predicate returns
`#t`if both of the following tests are satisfied in order: the lengths of the vectors are the same in the sense of`=`, and the elements of the vectors are the same in the sense of the equality predicate of`element-comparator`. - The ordering predicate returns
`#t`if the results of applying length to the first vector is less than the result of applying length to the second vector. If the lengths are equal, then the elements are examined pairwise using the ordering predicate of`element-comparator`. If any pair of elements returns`#t`, then that is the result of the list comparator's ordering predicate; otherwise the result is`#f` - The
`hash`function computes the hash values of the elements using the hash function of`element-comparator`and then hashes them together in an implementation-defined way.

Here is an example, which returns a comparator for byte vectors:

(make-vector-comparator (make-comparator exact-integer? = < number-hash) bytevector? bytevector-length bytevector-u8-ref)

- The type test returns
