Version 3 of the C++ Extensions for Library Fundamentals, ISO/IEC TS 19568:2024, defines the following new components for the C++ standard library, in addition to those defined inversion 1 andversion 2.
Components merged into C++17/20 and the following components are removed in LFTS v3:
Defined in header <experimental/scope> | |
| wraps a function object and invokes it on exiting the scope (class template)[edit] | |
| wraps a function object and invokes it on exiting the scope through an exception (class template)[edit] | |
| wraps a function object and invokes it on exiting the scope normally (class template)[edit] | |
| universal RAII resource handle wrapper (class template)[edit] | |
Defined in header <experimental/memory_resource> | |
__cpp_lib_experimental_memory_resources | a value of at least201803 indicates thatresource_adaptor is supported (macro constant) |
Defined in header <experimental/functional> | |
__cpp_lib_experimental_function_polymorphic_allocator | a value of at least202211 indicates thatstd::pmr::polymorphic_allocator<> is used forstd::experimental::function (macro constant) |
Defined in header <experimental/scope> | |
__cpp_lib_experimental_scope | a value of at least201902 indicates that the scope guards are supported (macro constant) |
The value of__cpp_lib_experimental_memory_resources has been increased in LFTS v3, because the design ofresource_adaptor is rebased ontostd::pmr::memory_resource.
