therealyingtong c43c91b796 gadget::utilities: Adjustments to utilities gadgets and helpers. 2021-06-25 15:05:39 +08:00
therealyingtong 3840f280d7 lookup_range_check.rs: Add short range check lookup. 
Also introduce a "strict" mode for the full-length lookup, where
"true" requires the field element to be within num_words * K bits,
whereas "false" does not.

therealyingtong b299a51b31 lookup_range_check.rs: Downgrade from Chip to Config. 
We need to be able to toggle the lookup on and off on specific
offsets. These offsets are often assigned outside the logic of
the decomposition.

therealyingtong e83880841a utilities::lookup_range_check: Add LookupRangeCheck chip 
This decomposes a field element into K-bit words and constrains each
word's range by looking it up in a K-bit lookup table.

The field element is broken down using a running sum. All interstitial
values of the running sum are returned.
