Implementations

impl PyConnectionResetError

pub fn new_err<A>(args: A) -> PyErr where
    A: PyErrArguments + Send + Sync + 'static, 

Methods from Deref<Target = PyAny>

pub fn downcast<T>(&self) -> Result<&T, PyDowncastError<'_>> where
    for<'py> T: PyTryFrom<'py>, 

Convert this PyAny to a concrete Python type.

pub fn hasattr<N>(&self, attr_name: N) -> PyResult<bool> where
    N: ToPyObject, 

Determines whether this object has the given attribute.

This is equivalent to the Python expression hasattr(self, attr_name).

pub fn getattr<N>(&self, attr_name: N) -> PyResult<&PyAny> where
    N: ToPyObject, 

Retrieves an attribute value.

This is equivalent to the Python expression self.attr_name.

pub fn setattr<N, V>(&self, attr_name: N, value: V) -> PyResult<()> where
    N: ToBorrowedObject,
    V: ToBorrowedObject, 

Sets an attribute value.

This is equivalent to the Python expression self.attr_name = value.

pub fn delattr<N>(&self, attr_name: N) -> PyResult<()> where
    N: ToPyObject, 

Deletes an attribute.

This is equivalent to the Python expression del self.attr_name.

pub fn compare<O>(&self, other: O) -> PyResult<Ordering> where
    O: ToPyObject, 

Compares two Python objects.

This is equivalent to:

if self == other:
    return Equal
elif a < b:
    return Less
elif a > b:
    return Greater
else:
    raise TypeError("PyAny::compare(): All comparisons returned false")

pub fn rich_compare<O>(
    &self,
    other: O,
    compare_op: CompareOp
) -> PyResult<&PyAny> where
    O: ToPyObject, 

Compares two Python objects.

Depending on the value of compare_op, this is equivalent to one of the following Python expressions:

• CompareOp::Eq: self == other
• CompareOp::Ne: self != other
• CompareOp::Lt: self < other
• CompareOp::Le: self <= other
• CompareOp::Gt: self > other
• CompareOp::Ge: self >= other

pub fn is_callable(&self) -> bool

Determines whether this object is callable.

pub fn call(
    &self,
    args: impl IntoPy<Py<PyTuple>>,
    kwargs: Option<&PyDict>
) -> PyResult<&PyAny>

Calls the object.

This is equivalent to the Python expression self(*args, **kwargs).

pub fn call0(&self) -> PyResult<&PyAny>

Calls the object without arguments.

This is equivalent to the Python expression self().

pub fn call1(&self, args: impl IntoPy<Py<PyTuple>>) -> PyResult<&PyAny>

Calls the object with only positional arguments.

This is equivalent to the Python expression self(*args).

pub fn call_method(
    &self,
    name: &str,
    args: impl IntoPy<Py<PyTuple>>,
    kwargs: Option<&PyDict>
) -> PyResult<&PyAny>

Calls a method on the object.

This is equivalent to the Python expression self.name(*args, **kwargs).

Example

use pyo3::types::IntoPyDict;

let gil = Python::acquire_gil();
let py = gil.python();
let list = vec![3, 6, 5, 4, 7].to_object(py);
let dict = vec![("reverse", true)].into_py_dict(py);
list.call_method(py, "sort", (), Some(dict)).unwrap();
assert_eq!(list.extract::<Vec<i32>>(py).unwrap(), vec![7, 6, 5, 4, 3]);

let new_element = 1.to_object(py);
list.call_method(py, "append", (new_element,), None).unwrap();
assert_eq!(list.extract::<Vec<i32>>(py).unwrap(), vec![7, 6, 5, 4, 3, 1]);

pub fn call_method0(&self, name: &str) -> PyResult<&PyAny>

Calls a method on the object without arguments.

This is equivalent to the Python expression self.name().

pub fn call_method1(
    &self,
    name: &str,
    args: impl IntoPy<Py<PyTuple>>
) -> PyResult<&PyAny>

Calls a method on the object with only positional arguments.

This is equivalent to the Python expression self.name(*args).

pub fn is_true(&self) -> PyResult<bool>

This is equivalent to the Python expression bool(self).

pub fn is_none(&self) -> bool

Returns whether the object is considered to be None.

This is equivalent to the Python expression self is None.

pub fn is_empty(&self) -> PyResult<bool>

Returns true if the sequence or mapping has a length of 0.

This is equivalent to the Python expression len(self) == 0.

pub fn get_item<K>(&self, key: K) -> PyResult<&PyAny> where
    K: ToBorrowedObject, 

Gets an item from the collection.

This is equivalent to the Python expression self[key].

pub fn set_item<K, V>(&self, key: K, value: V) -> PyResult<()> where
    K: ToBorrowedObject,
    V: ToBorrowedObject, 

Sets a collection item value.

This is equivalent to the Python expression self[key] = value.

pub fn del_item<K>(&self, key: K) -> PyResult<()> where
    K: ToBorrowedObject, 

Deletes an item from the collection.

This is equivalent to the Python expression del self[key].

pub fn iter(&self) -> PyResult<&PyIterator>

Takes an object and returns an iterator for it.

This is typically a new iterator but if the argument is an iterator, this returns itself.

pub fn get_type(&self) -> &PyType

Returns the Python type object for this object’s type.

pub fn get_type_ptr(&self) -> *mut PyTypeObject

Returns the Python type pointer for this object.

pub fn cast_as<'a, D>(&'a self) -> Result<&'a D, PyDowncastError<'_>> where
    D: PyTryFrom<'a>, 

Casts the PyObject to a concrete Python object type.

This can cast only to native Python types, not types implemented in Rust.

pub fn extract<'a, D>(&'a self) -> PyResult<D> where
    D: FromPyObject<'a>, 

Extracts some type from the Python object.

This is a wrapper function around FromPyObject::extract().

pub fn get_refcnt(&self) -> isize

Returns the reference count for the Python object.

pub fn repr(&self) -> PyResult<&PyString>

Computes the “repr” representation of self.

This is equivalent to the Python expression repr(self).

pub fn str(&self) -> PyResult<&PyString>

Computes the “str” representation of self.

This is equivalent to the Python expression str(self).

pub fn hash(&self) -> PyResult<isize>

Retrieves the hash code of self.

This is equivalent to the Python expression hash(self).

pub fn len(&self) -> PyResult<usize>

Returns the length of the sequence or mapping.

This is equivalent to the Python expression len(self).

pub fn dir(&self) -> &PyList

Returns the list of attributes of this object.

This is equivalent to the Python expression dir(self).

pub fn is_instance<T: PyTypeObject>(&self) -> PyResult<bool>

Checks whether this object is an instance of type T.

This is equivalent to the Python expression isinstance(self, T).
