Detailed Description

template<unsigned int C>
struct pabigot::crc::details::uint_size_traits< C >

Entry-point to identifying unsigned integral types supporting a specific number of bits.

The concept here is derived from the approach in boost::integer, simplified by excluding signed types and exact representations; restricted by relying on the types in <cstdint> instead of native types; and possibly improved by not assuming the least and fast types are the same:

• width is the number of bits in the value;
• fast_type is the fast unsigned type for width bits. This is highly likely to have more than width bits; keep this in mind when byte-swapping values.
• least_type is the least unsigned type for width bits. When width is not a power of 2 this is highly likely to have more than width bits; keep this in mind when byte-swapping values.

Template Parameters

C	a category value: 1 for 64 bit, 2 for 32 bit, 3 for 16 bit, and 4 for 8 bit. A specialization is provided for each of these.
