Detailed Description

Literal constants for data size quantities.

These functions allow a simplified syntax for specifying a data size quantity. In order to use these, their namespace must be used:

using namespace util::quantities::datasize_literals;

// definition of `util::quantities::byte` constant:
constexpr auto s_B = 12_B;

// assignment (likely to a quantity) of
// `util::quantities::kibibyte{512}`
s_B = 512_kiB;
