Macro Definition Documentation

◆ PYBIND11_BUILD_ABI

#define PYBIND11_BUILD_ABI ""

On Linux/OSX, changes in GXX_ABI_VERSION indicate ABI incompatibility.

Definition at line 268 of file internals.h.

◆ PYBIND11_BUILD_TYPE

#define PYBIND11_BUILD_TYPE ""

On MSVC, debug and release builds are not ABI-compatible!

Definition at line 226 of file internals.h.

◆ PYBIND11_COMPILER_TYPE

#define PYBIND11_COMPILER_TYPE "_unknown"

Let's assume that different compilers are ABI-incompatible. A user can manually set this string if they know their compiler is compatible.

Definition at line 248 of file internals.h.

◆ PYBIND11_INTERNALS_ID

#define PYBIND11_INTERNALS_ID

Value:

"__pybind11_internals_v" PYBIND11_TOSTRING(PYBIND11_INTERNALS_VERSION)                        \
        PYBIND11_INTERNALS_KIND PYBIND11_COMPILER_TYPE PYBIND11_STDLIB PYBIND11_BUILD_ABI         \
            PYBIND11_BUILD_TYPE "__"

Definition at line 280 of file internals.h.

◆ PYBIND11_INTERNALS_KIND

#define PYBIND11_INTERNALS_KIND "_without_thread"

Definition at line 276 of file internals.h.

◆ PYBIND11_INTERNALS_VERSION

#define PYBIND11_INTERNALS_VERSION 4

Tracks the internals and type_info ABI version independent of the main library version.

Some portions of the code use an ABI that is conditional depending on this version number. That allows ABI-breaking changes to be "pre-implemented". Once the default version number is incremented, the conditional logic that no longer applies can be removed. Additionally, users that need not maintain ABI compatibility can increase the version number in order to take advantage of any functionality/efficiency improvements that depend on the newer ABI.

WARNING: If you choose to manually increase the ABI version, note that pybind11 may not be tested as thoroughly with a non-default ABI version, and further ABI-incompatible changes may be made before the ABI is officially changed to the new version.

Definition at line 31 of file internals.h.

◆ PYBIND11_MODULE_LOCAL_ID

#define PYBIND11_MODULE_LOCAL_ID

Value:

Typedef Documentation

◆ ExceptionTranslator

using ExceptionTranslator = void (*)(std::exception_ptr)

Definition at line 36 of file internals.h.

◆ type_map

template<typename value_type >

using type_map = std::unordered_map<std::type_index, value_type, type_hash, type_equal_to>

Definition at line 137 of file internals.h.

Function Documentation

◆ c_str()

template<typename... Args>

const char* c_str ( Args &&... args )

Constructs a std::string with the given arguments, stores it in internals, and returns its c_str(). Such strings objects have a long storage duration – the internal strings are only cleared when the program exits or after interpreter shutdown (when embedding), and so are suitable for c-style strings needed by Python internals (such as PyTypeObject's tp_name).

Definition at line 524 of file internals.h.

◆ get_internals()

PYBIND11_NOINLINE internals& get_internals ( )

Return a reference to the current internals data.

Definition at line 405 of file internals.h.

◆ get_internals_pp()

internals**& get_internals_pp ( )

inline

Each module locally stores a pointer to the internals data. The data itself is shared among modules with the same PYBIND11_INTERNALS_ID.

Definition at line 292 of file internals.h.

◆ get_local_internals()

local_internals& get_local_internals ( )

inline

Works like get_internals, but for things which are locally registered.

Definition at line 514 of file internals.h.

◆ get_or_create_shared_data()

template<typename T >

T& get_or_create_shared_data ( const std::string & name )

Returns a typed reference to a shared data entry (by using get_shared_data()) if such entry exists. Otherwise, a new object of default-constructible type T is added to the shared data under the given name and a reference to it is returned.

Definition at line 551 of file internals.h.

◆ get_shared_data()

PYBIND11_NOINLINE void* get_shared_data ( const std::string & name )

Returns a named pointer that is shared among all extension modules (using the same pybind11 version) running in the current interpreter. Names starting with underscores are reserved for internal usage. Returns nullptr if no matching entry was found.

Definition at line 535 of file internals.h.

◆ handle_nested_exception()

template<class T , enable_if_t< std::is_same< std::nested_exception, remove_cvref_t< T >>::value, int > = 0>

bool handle_nested_exception	(	const T &	exc,
		const std::exception_ptr &	p
	)

Definition at line 302 of file internals.h.

◆ make_default_metaclass()

PyTypeObject* make_default_metaclass ( )

inline

This metaclass is assigned by default to all pybind11 types and is required in order for static properties to function correctly. Users may override this using py::metaclass. Return value: New reference.

Definition at line 241 of file class.h.

◆ make_object_base_type()

PyObject* make_object_base_type ( PyTypeObject * metaclass )

inline

Create the type which can be used as a common base for all classes. This is needed in order to satisfy Python's requirements for multiple inheritance. Return value: New reference.

Definition at line 463 of file class.h.

◆ make_static_property_type()

PyTypeObject* make_static_property_type ( )

inline

A static_property is the same as a property but the __get__() and __set__() methods are modified to always use the object type instead of a concrete instance. Return value: New reference.

Definition at line 61 of file class.h.

◆ raise_err()

bool raise_err	(	PyObject *	exc_type,
		const char *	msg
	)

inline

Definition at line 320 of file internals.h.

◆ same_type()

bool same_type	(	const std::type_info &	lhs,
		const std::type_info &	rhs
	)

inline

Definition at line 114 of file internals.h.

◆ set_shared_data()

PYBIND11_NOINLINE void* set_shared_data	(	const std::string &	name,
		void *	data
	)

Set the shared data that can be later recovered by get_shared_data().

Definition at line 542 of file internals.h.

◆ translate_exception()

void translate_exception ( std::exception_ptr p )

inline

Definition at line 329 of file internals.h.

◆ translate_local_exception()

void translate_local_exception ( std::exception_ptr p )

inline

Definition at line 389 of file internals.h.
