C++11 implementations of standard components added in later C++ standards.
Boost.Compat is a repository of C++11 implementations of standard components added in later C++ standards. Its target audience is Boost library authors whose libraries support a lower C++ standard, but wish to utilize a component added in a subsequent one.
The criteria for inclusion in Boost.Compat are as follows:
- The implementation should be relatively simple and header-only.
- The component must implement the standard functionality
exactly, without deviations or extensions. This allows
(but does not require) the implementation to be a simple
usingdeclaration in case the standard component is available.
- The component must not depend on any Boost libraries except Boost.Config, Boost.Assert, or Boost.ThrowException.
- The component must not be a vocabulary type, visible in
the library APIs. The user should never see a
boost::compattype; the use of Compat types should be confined to library implementations.
