TinyUtils

A header-only library of modern C++ idioms

For example:

• Fast pImpl (Pointer To Implementation)
  • Zero overhead cost implementation

class Book final
{
public:
  std::string const& contents();
private:
  std::string contents_;
};

#include <tiny_utils/fast_pimpl.h>

class Book final
{
public:
    std::string const& contents();
private:
    struct implementation;
    static int constexpr length{24};
    static int constexpr alignment{8};
    tiny_utils::fast_pimpl_t<implementation, length, alignment, false> impl_;
};

If we are using Microsoft C++ (MSVC), we should use tiny_utils::length(40, 32, 24) because Debug and Release have different values of sizeof(Book).

#include <tiny_utils/fast_pimpl.h>

class Book final
{
public:
    std::string const& contents();
private:
    struct implementation;
    static int constexpr length = tiny_utils::length(40, 32, 24);
    static int constexpr alignment{8};
    tiny_utils::fast_pimpl_t<implementation, length, alignment, false> impl_;
};
