Module trampoline 

Trampolines for various pyfunction and pymethod implementations.

They exist to monomorphise std::panic::catch_unwind once into PyO3, rather than inline in every function, thus saving a huge amount of compile-time complexity.

Traits

MethodDef

A workaround for Rust not allowing function pointers as const generics: define a trait which has a constant function pointer.

Functions

binaryfunc^⚠

External symbol called by Python, which calls the provided Rust function.

Noargs is a special case where the _args parameter is unused and not passed to the inner Func.

objobjproc^⚠

External symbol called by Python, which calls the provided Rust function.

panic_result_into_callback_output 🔒

Converts the output of std::panic::catch_unwind into a Python function output, either by raising a Python exception or by unwrapping the contained success output.

releasebufferproc^⚠Non-Py_LIMITED_API or Py_3_11

Releasebufferproc is a special case where the function cannot return an error, so we use trampoline_unraisable.

ternaryfunc^⚠

External symbol called by Python, which calls the provided Rust function.

trampoline 🔒 ^⚠

Implementation of trampoline functions, which sets up an AttachGuard and calls F.

trampoline_unraisable 🔒 ^⚠

Implementation of trampoline for functions which can’t return an error.

unaryfunc^⚠

External symbol called by Python, which calls the provided Rust function.
