Detailed Description

The encode source: the codecs read the record vector through this.

getInt returns a signed-widened integer (range scan, bit packing); getSlot returns the 32-bit pallet/common/None slot (an integer truncated to 32 bits, or a float's bit pattern); getString the string value. The element index follows the RecordSink convention. ErasedRecordSource implements it over a const std::vector<Record>&.
