multi-checksum

Vocabulary

checksums.multi

Class description

This is an instance of the block-checksum mixin. It calculates multiple checksums by sequentially passing the data it receives to all the checksums in its 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.
