+
+.. start
+
+
+**pybind11** is a lightweight header-only library that exposes C++ types
+in Python and vice versa, mainly to create Python bindings of existing
+C++ code. Its goals and syntax are similar to the excellent
+`Boost.Python <http://www.boost.org/doc/libs/1_58_0/libs/python/doc/>`_
+library by David Abrahams: to minimize boilerplate code in traditional
+extension modules by inferring type information using compile-time
+introspection.
+
+The main issue with Boost.Python—and the reason for creating such a
+similar project—is Boost. Boost is an enormously large and complex suite
+of utility libraries that works with almost every C++ compiler in
+existence. This compatibility has its cost: arcane template tricks and
+workarounds are necessary to support the oldest and buggiest of compiler
+specimens. Now that C++11-compatible compilers are widely available,
+this heavy machinery has become an excessively large and unnecessary
+dependency.
+
+Think of this library as a tiny self-contained version of Boost.Python
+with everything stripped away that isn't relevant for binding
+generation. Without comments, the core header files only require ~4K
+lines of code and depend on Python (CPython 3.8+, PyPy, or GraalPy) and the C++
+standard library. This compact implementation was possible thanks to some C++11
+language features (specifically: tuples, lambda functions and variadic
+templates). Since its creation, this library has grown beyond Boost.Python in
+many ways, leading to dramatically simpler binding code in many common
+situations.
+
+Tutorial and reference documentation is provided at
+`pybind11.readthedocs.io <https://pybind11.readthedocs.io/en/latest>`_.
+A PDF version of the manual is available
+`here <https://pybind11.readthedocs.io/_/downloads/en/latest/pdf/>`_.
+And the source code is always available at
+`github.com/pybind/pybind11 <https://github.com/pybind/pybind11>`_.
+
+
+Core features
+-------------
+
+
+pybind11 can map the following core C++ features to Python:
+
+- Functions accepting and returning custom data structures per value,
+  reference, or pointer
+- Instance methods and static methods
+- Overloaded functions
+- Instance attributes and static attributes
+- Arbitrary exception types
+- Enumerations
+- Callbacks
+- Iterators and ranges
+- Custom operators
+- Single and multiple inheritance
+- STL data structures
+- Smart pointers with reference counting like ``std::shared_ptr``
+- Internal references with correct reference counting
+- C++ classes with virtual (and pure virtual) methods can be extended
+  in Python
+- Integrated NumPy support (NumPy 2 requires pybind11 2.12+)
+
+Goodies
+-------
+
+In addition to the core functionality, pybind11 provides some extra
+goodies:
+
+- CPython 3.8+, PyPy3 7.3.17+, and GraalPy 24.1+ are supported with an
+  implementation-agnostic interface (see older versions for older CPython
+  and PyPy versions).
+
+- It is possible to bind C++11 lambda functions with captured
+  variables. The lambda capture data is stored inside the resulting
+  Python function object.
+
+- pybind11 uses C++11 move constructors and move assignment operators
+  whenever possible to efficiently transfer custom data types.
+
+- It's easy to expose the internal storage of custom data types through
+  Pythons' buffer protocols. This is handy e.g. for fast conversion
+  between C++ matrix classes like Eigen and NumPy without expensive
+  copy operations.
+
+- pybind11 can automatically vectorize functions so that they are
+  transparently applied to all entries of one or more NumPy array
+  arguments.
+
+- Python's slice-based access and assignment operations can be
+  supported with just a few lines of code.
+
+- Everything is contained in just a few header files; there is no need
+  to link against any additional libraries.
+
+- Binaries are generally smaller by a factor of at least 2 compared to
+  equivalent bindings generated by Boost.Python. A recent pybind11
+  conversion of PyRosetta, an enormous Boost.Python binding project,
+  `reported <https://graylab.jhu.edu/Sergey/2016.RosettaCon/PyRosetta-4.pdf>`_
+  a binary size reduction of **5.4x** and compile time reduction by
+  **5.8x**.
+
+- Function signatures are precomputed at compile time (using
+  ``constexpr``), leading to smaller binaries.
+
+- With little extra effort, C++ types can be pickled and unpickled
+  similar to regular Python objects.

+/* The pybind11_conduit_v1 feature enables type-safe interoperability between
+
+* different independent Python/C++ bindings systems,
+
+* including pybind11 versions with different PYBIND11_INTERNALS_VERSION's.
+
+    * NOTE: The conduit feature
+            only covers    from-Python-to-C++ conversions, it
+            does not cover from-C++-to-Python conversions.
+            (For the latter, a different feature would have to be added.)
+
+The naming of the feature is a bit misleading:
+
+* The feature is in no way tied to pybind11 internals.
+
+* It just happens to originate from pybind11 and currently still lives there.
+
+* The only external dependency is <Python.h>.
+
+The implementation is a VERY light-weight dependency. It is designed to be
+compatible with any ISO C++11 (or higher) compiler, and does NOT require
+C++ Exception Handling to be enabled.
+
+Please see https://github.com/pybind/pybind11/pull/5296 for more background.
+
+The implementation involves a
+
+def _pybind11_conduit_v1_(
+    self,
+    pybind11_platform_abi_id: bytes,
+    cpp_type_info_capsule: capsule,
+    pointer_kind: bytes) -> capsule
+
+method that is meant to be added to Python objects wrapping C++ objects
+(e.g. pybind11::class_-wrapped types).
+
+The design of the _pybind11_conduit_v1_ feature provides two layers of
+protection against C++ ABI mismatches:
+
+* The first and most important layer is that the pybind11_platform_abi_id's
+  must match between extensions. — This will never be perfect, but is the same
+  pragmatic approach used in pybind11 since 2017
+  (https://github.com/pybind/pybind11/commit/96997a4b9d4ec3d389a570604394af5d5eee2557,
+  PYBIND11_INTERNALS_ID).
+
+* The second layer is that the typeid(std::type_info).name()'s must match
+  between extensions.
+
+The implementation below (which is shorter than this comment!), serves as a
+battle-tested specification. The main API is this one function:
+
+auto *cpp_pointer = pybind11_conduit_v1::get_type_pointer_ephemeral<YourType>(py_obj);
+
+It is meant to be a minimalistic reference implementation, intentionally
+without comprehensive error reporting. It is expected that major bindings
+systems will roll their own, compatible implementations, potentially with
+system-specific error reporting. The essential specifications all bindings
+systems need to agree on are merely:
+
+* PYBIND11_PLATFORM_ABI_ID (const char* literal).
+
+* The cpp_type_info capsule (see below: a void *ptr and a const char *name).
+
+* The cpp_conduit capsule (see below: a void *ptr and a const char *name).
+
+* "raw_pointer_ephemeral" means: the lifetime of the pointer is the lifetime
+  of the py_obj.

+/* Proof-of-Concept for smart pointer interoperability.
+
+High-level aspects:
+
+* Support all `unique_ptr`, `shared_ptr` interops that are feasible.
+
+* Cleanly and clearly report all interops that are infeasible.
+
+* Meant to fit into a `PyObject`, as a holder for C++ objects.
+
+* Support a system design that makes it impossible to trigger
+  C++ Undefined Behavior, especially from Python.
+
+* Support a system design with clean runtime inheritance casting. From this
+  it follows that the `smart_holder` needs to be type-erased (`void*`).
+
+* Handling of RTTI for the type-erased held pointer is NOT implemented here.
+  It is the responsibility of the caller to ensure that `static_cast<T *>`
+  is well-formed when calling `as_*` member functions. Inheritance casting
+  needs to be handled in a different layer (similar to the code organization
+  in boost/python/object/inheritance.hpp).
+
+Details:
+
+* The "root holder" chosen here is a `shared_ptr<void>` (named `vptr` in this
+  implementation). This choice is practically inevitable because `shared_ptr`
+  has only very limited support for inspecting and accessing its deleter.
+
+* If created from a raw pointer, or a `unique_ptr` without a custom deleter,
+  `vptr` always uses a custom deleter, to support `unique_ptr`-like disowning.
+  The custom deleters could be extended to included life-time management for
+  external objects (e.g. `PyObject`).
+
+* If created from an external `shared_ptr`, or a `unique_ptr` with a custom
+  deleter, including life-time management for external objects is infeasible.
+
+* By choice, the smart_holder is movable but not copyable, to keep the design
+  simple, and to guard against accidental copying overhead.
+
+* The `void_cast_raw_ptr` option is needed to make the `smart_holder` `vptr`
+  member invisible to the `shared_from_this` mechanism, in case the lifetime
+  of a `PyObject` is tied to the pointee.

+ * 1. When acquiring the GIL from an non-main thread during the finalization
+ *    phase, the GILState API blindly terminates the calling thread, which
+ *    is often not what is wanted. This API does not do this.
+ *
+ * 2. The gil_scoped_release function can optionally cut the relationship
+ *    of a PyThreadState and its associated thread, which allows moving it to
+ *    another thread (this is a fairly rare/advanced use case).
+ *
+ * 3. The reference count of an acquired thread state can be controlled. This
+ *    can be handy to prevent cases where callbacks issued from an external
+ *    thread would otherwise constantly construct and destroy thread state data
+ *    structures.
+ *
+ * See the Python bindings of NanoGUI (http://github.com/wjakob/nanogui) for an
+ * example which uses features 2 and 3 to migrate the Python thread of
+ * execution to another thread (to run the event loop on the original thread,

+/*
+The three `object_is_convertible_to_*()` functions below are
+the result of converging the behaviors of pybind11 and PyCLIF
+(http://github.com/google/clif).
+
+Originally PyCLIF was extremely far on the permissive side of the spectrum,
+while pybind11 was very far on the strict side. Originally PyCLIF accepted any
+Python iterable as input for a C++ `vector`/`set`/`map` argument, as long as
+the elements were convertible. The obvious (in hindsight) problem was that
+any empty Python iterable could be passed to any of these C++ types, e.g. `{}`
+was accepted for C++ `vector`/`set` arguments, or `[]` for C++ `map` arguments.
+
+The functions below strike a practical permissive-vs-strict compromise,
+informed by tens of thousands of use cases in the wild. A main objective is
+to prevent accidents and improve readability:
+
+- Python literals must match the C++ types.
+
+- For C++ `set`: The potentially reducing conversion from a Python sequence
+  (e.g. Python `list` or `tuple`) to a C++ `set` must be explicit, by going
+  through a Python `set`.
+
+- However, a Python `set` can still be passed to a C++ `vector`. The rationale
+  is that this conversion is not reducing. Implicit conversions of this kind
+  are also fairly commonly used, therefore enforcing explicit conversions
+  would have an unfavorable cost : benefit ratio; more sloppily speaking,
+  such an enforcement would be more annoying than helpful.
+
+Additional checks have been added to allow types derived from `collections.abc.Set` and
+`collections.abc.Mapping` (`collections.abc.Sequence` is already allowed by `PySequence_Check`).
