the template basic_ring_buffer<ContainerType>, defined in <ring-buffer.h>
augments an existing container to be used as a ring buffer
the alias template ring_buffer<ValueType, Size>, defined in <ring-buffer.h>
an alias for basic_ring_buffer<std::array<ValueType, Size>>
the template ring_buffer_iterator<ContainerType>, defined in <ring-buffer-iterator.h>
a random access iterator over a basic_ring_buffer with the same container type
the template ring_buffer_const_iterator<ContainerType>, defined in <ring-buffer-iterator.h>
a random access iterator over a basic_ring_buffer with the same container type, giving const access to the elements

This project can be configured via CMake options or preprocessor defines

CMake options

RING_BUFFER_DEFAULT_CXXFLAGS (default OFF)
set the C++ compiler flags to -Wall -Wextra, and try to detect the newest supported C++ standard.
RING_BUFFER_BUILD_TESTS (default OFF)
build the test programs from the test/ subdirectory
RING_BUFFER_FEATURE_DETECT (default ON)
try to detect the values for the following feature options automatically
RING_BUFFER_NOEXCEPT (default OFF)
enable use of the noexcept(bool-expr) conditional noexcept operator (needs C++11)
RING_BUFFER_CONSTEXPR (default OFF)
make all member functions of basic_ring_buffer and its iterators constexpr (needs C++14)
RING_BUFFER_CONSTEXPR_DESTRUCTORS (default OFF)
make the destructors of basic_ring_buffer and its iterators explicitly constexpr (needs C++20)

The last 3 options set preprocessor defines with the same name when enabled.
