Module extract_argument

Structs§

DictVarkeywords: Marker struct which indicates unknown keywords should be collected into a PyDict.
FunctionDescription: Function argument specification for a #[pyfunction] or #[pymethod].
KeywordOnlyParameterDescription
NoVarargs: Marker struct which indicates varargs are not allowed.
NoVarkeywords: Marker struct which indicates unknown keywords are not permitted.
TupleVarargs: Marker struct which indicates varargs should be collected into a PyTuple.

FunctionArgumentHolder: Trait for types which can be a function argument holder - they should to be able to const-initialize to an empty value.
PyFunctionArgument: A trait which is used to help PyO3 macros extract function arguments.
VarargsHandler: A trait used to control whether to accept varargs in FunctionDescription::extract_argument_(method) functions.
VarkeywordsHandler: A trait used to control whether to accept varkeywords in FunctionDescription::extract_argument_(method) functions.

argument_extraction_error 👻: Adds the argument name to the error message of an error which occurred during argument extraction.
extract_argument 👻: The standard implementation of how PyO3 extracts a #[pyfunction] or #[pymethod] function argument.
extract_argument_with_default 👻: Alternative to extract_argument used when the argument has a default value provided by an annotation.
extract_optional_argument 👻: Alternative to extract_argument used for Option<T> arguments. This is necessary because Option<&T> does not implement PyFunctionArgument for T: PyClass.
extract_pyclass_ref
extract_pyclass_ref_mut
from_py_with 👻: Alternative to extract_argument used when the argument has a #[pyo3(from_py_with)] annotation.
from_py_with_with_default 👻: Alternative to extract_argument used when the argument has a #[pyo3(from_py_with)] annotation and also a default value.
push_parameter_list 🔒
unwrap_required_argument 👻 ^⚠: Unwraps the Option<&PyAny> produced by the FunctionDescription extract_arguments_ methods. They check if required methods are all provided.
