Like collection-hash, only a more efficient version just for sequences. This is similar to an equal-hash for the collection, except that it hashes things with ordered: #t and ignores the sequence keys.
USE WITH CAUTION: This isn’t a proper equal-hash because two collections of different types but identical key/element pairs won’t generate the same hash id, even though the two collections are =.
| element-hash | An instance of <function>. Computes hash ids for the elements. It takes an object and a <hash-state> as the arguments, and returns a hash id and a hash state. |
| seq | An instance of <sequence>. |
| initial-state | An instance of <hash-state>. |
| hash-id | An instance of <integer>. |
| hash-state | An instance of <hash-state>. |
