Attribute Macro pyfunction
#[pyfunction]Expand description
A proc macro used to expose Rust functions to Python.
Functions annotated with #[pyfunction] can also be annotated with the following #[pyo3]
options:
| Annotation | Description |
|---|---|
#[pyo3(name = "...")] | Defines the name of the function in Python. |
#[pyo3(text_signature = "...")] | Defines the __text_signature__ attribute of the function in Python. |
#[pyo3(pass_module)] | Passes the module containing the function as a &PyModule first argument to the function. |
For more on exposing functions see the function section of the guide.
Due to technical limitations on how #[pyfunction] is implemented, a function marked
#[pyfunction] cannot have a module with the same name in the same scope. (The
#[pyfunction] implementation generates a hidden module with the same name containing
metadata about the function, which is used by wrap_pyfunction!).
