Detailed Description

template<typename TArrayExtents, typename TRecordDim, typename Bits = typename TArrayExtents::value_type, SignBit SignBit = SignBit::Keep, typename TLinearizeArrayIndexFunctor = LinearizeArrayIndexRight, typename TStoredIntegral = internal::StoredUnsignedFor<TRecordDim>>
struct llama::mapping::BitPackedIntSoA< TArrayExtents, TRecordDim, Bits, SignBit, TLinearizeArrayIndexFunctor, TStoredIntegral >

Struct of array mapping using bit packing to reduce size/precision of integral data types. If your record dimension contains non-integral types, split them off using the Split mapping first.

Template Parameters

Bits	If Bits is llama::Constant<N>, the compile-time N specifies the number of bits to use. If Bits is an integral type T, the number of bits is specified at runtime, passed to the constructor and stored as type T. Must not be zero and must not be bigger than the bits of TStoredIntegral.
SignBit	When set to SignBit::Discard, discards the sign bit when storing signed integers. All numbers will be read back positive.
TLinearizeArrayIndexFunctor	Defines how the array dimensions should be mapped into linear numbers and how big the linear domain gets.
TStoredIntegral	Integral type used as storage of reduced precision integers. Must be std::uint32_t or std::uint64_t.
