Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Alexandrescu, C++
Coding Standards
This is an older version of Boost and was released in 2021. The current version is 1.90.0.
The type of memory resource used by the library.
Defined in header <boost/json/memory_resource.hpp>
class memory_resource
This type alias is set depending on how the library is configured:
If the macro BOOST_JSON_STANDALONE
is not defined, this type will be an alias for boost::container::pmr::memory_resource. Compiling a program using
the library will require Boost, and a compiler conforming to C++11 or later.
If the macro BOOST_JSON_STANDALONE
is defined, this type will be an alias for std::pmr::memory_resource. Compiling a program using
the library will require only a compiler conforming to C++17 or later.
