Detailed Description

template<class DataType>
class bb::plookup::ReadData< DataType >

Container type for lookup table reads.

Template Parameters

DataType

a native or stdlib field type, or the witness index type uint32_t

We us this approach to indexing, using enums, rather than to make member variables column_i, to minimize code changes; both non-const and const versions are in use.

The inner index, i.e., the index of each vector v in the array columns, could also be treated as an enum, but that might be messier. Note that v[0] represents a full accumulated sum, v[1] represents one step before that, and so on. See the documentation of the native version of get_lookup_accumulators.
