{ $class-description "This is an instance of the " { $link block-checksum } " mixin. It calculates multiple checksums by sequentially passing the data it receives to all the checksums in its " { $slot "checksums" } " slot. This way, even though the individual checksums are not calculated in parallel, you still can have the performance benefits of only reading a disk file once, or not having to temporarily store the data streamed from a network." } ;
HELP: multi-state
{ $class-description "This class represents the current state of a " { $link multi-checksum } " checksum calculation. It has an array of associated checksum states until it is disposed. You may call " { $link add-checksum-bytes } " multiple times to pipe data to all the checksums in the " { $slot "checksums" } " slot. When finished, call " { $link get-checksum } " to receive the results and release implementation-specific resources, or " { $link dispose } " to release the resources and discard the result. After the first " { $link get-checksum } " call the returned value is stored in the " { $slot "results" } " slot, and subsequent calls return the same value." }

"Most code should use " { $link with-checksum-state } " to make sure the resources are properly disposed of. Higher level words like " { $link checksum-bytes } " and " { $link checksum-stream } " use it to perform the disposal." } ;
