Trait PyCallArgs

pub trait PyCallArgs<'py>: Sized + Sealed { }

This trait marks types that can be used as arguments to Python function calls.

This trait is currently implemented for Rust tuple (up to a size of 12), [Bound<'py, PyTuple>] and Py<PyTuple>. Custom types that are convertable to PyTuple via IntoPyObject need to do so before passing it to call.

This trait is not intended to used by downstream crates directly. As such it has no publicly available methods and cannot be implemented ouside of pyo3. The corresponding public API is available through call (call0, call1 and friends) on PyAnyMethods.

What is PyCallArgs used for?

PyCallArgs is used internally in pyo3 to dispatch the Python calls in the most optimal way for the current build configuration. Certain types, such as Rust tuples, do allow the usage of a faster calling convention of the Python interpreter (if available). More types that may take advantage from this may be added in the future.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
