Expand description

This trait represents the Python APIs which are usable on all Python objects.

It is recommended you import this trait via use pyo3::prelude::* rather than by importing this trait directly.

Required Methods§

source

fn is<T: AsPyPointer>(&self, other: &T) -> bool

Returns whether self and other point to the same object. To compare the equality of two objects (the == operator), use eq.

This is equivalent to the Python expression self is other.

source

fn hasattr<N>(&self, attr_name: N) -> PyResult<bool>
where N: IntoPy<Py<PyString>>,

Determines whether this object has the given attribute.

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern attr_name.

§Example: intern!ing the attribute name
#[pyfunction]
fn has_version(sys: &Bound<'_, PyModule>) -> PyResult<bool> {
    sys.hasattr(intern!(sys.py(), "version"))
}
source

fn getattr<N>(&self, attr_name: N) -> PyResult<Bound<'py, PyAny>>
where N: IntoPy<Py<PyString>>,

Retrieves an attribute value.

This is equivalent to the Python expression self.attr_name.

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern attr_name.

§Example: intern!ing the attribute name
#[pyfunction]
fn version<'py>(sys: &Bound<'py, PyModule>) -> PyResult<Bound<'py, PyAny>> {
    sys.getattr(intern!(sys.py(), "version"))
}
source

fn setattr<N, V>(&self, attr_name: N, value: V) -> PyResult<()>
where N: IntoPy<Py<PyString>>, V: ToPyObject,

Sets an attribute value.

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern name.

§Example: intern!ing the attribute name
#[pyfunction]
fn set_answer(ob: &Bound<'_, PyAny>) -> PyResult<()> {
    ob.setattr(intern!(ob.py(), "answer"), 42)
}
source

fn delattr<N>(&self, attr_name: N) -> PyResult<()>
where N: IntoPy<Py<PyString>>,

Deletes an attribute.

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern attr_name.

source

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

Returns an Ordering between self and other.

This is equivalent to the following Python code:

if self == other:
    return Equal
elif a < b:
    return Less
elif a > b:
    return Greater
else:
    raise TypeError("PyAny::compare(): All comparisons returned false")
§Examples
use pyo3::prelude::*;
use pyo3::types::PyFloat;
use std::cmp::Ordering;

Python::with_gil(|py| -> PyResult<()> {
    let a = PyFloat::new_bound(py, 0_f64);
    let b = PyFloat::new_bound(py, 42_f64);
    assert_eq!(a.compare(b)?, Ordering::Less);
    Ok(())
})?;

It will return PyErr for values that cannot be compared:

use pyo3::prelude::*;
use pyo3::types::{PyFloat, PyString};

Python::with_gil(|py| -> PyResult<()> {
    let a = PyFloat::new_bound(py, 0_f64);
    let b = PyString::new_bound(py, "zero");
    assert!(a.compare(b).is_err());
    Ok(())
})?;
source

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

Tests whether two Python objects obey a given CompareOp.

lt, le, eq, ne, gt and ge are the specialized versions of this function.

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

compare_opPython expression
CompareOp::Eqself == other
CompareOp::Neself != other
CompareOp::Ltself < other
CompareOp::Leself <= other
CompareOp::Gtself > other
CompareOp::Geself >= other
§Examples
use pyo3::class::basic::CompareOp;
use pyo3::prelude::*;
use pyo3::types::PyInt;

Python::with_gil(|py| -> PyResult<()> {
    let a: Bound<'_, PyInt> = 0_u8.into_py(py).into_bound(py).downcast_into()?;
    let b: Bound<'_, PyInt> = 42_u8.into_py(py).into_bound(py).downcast_into()?;
    assert!(a.rich_compare(b, CompareOp::Le)?.is_truthy()?);
    Ok(())
})?;
source

This is equivalent to the Python expression self < other.

source

fn le<O>(&self, other: O) -> PyResult<bool>
where O: ToPyObject,

This is equivalent to the Python expression self != other.

source

where O: ToPyObject,

Tests whether this object is greater than another.

This is equivalent to the Python expression self > other.

source

fn ge<O>(&self, other: O) -> PyResult<bool>
where O: ToPyObject,

Tests whether this object is greater than or equal to another.

This is equivalent to the Python expression self >= other.

source

fn add<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

Computes self + other.

source

fn sub<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

Computes self - other.

source

where O: ToPyObject,

Computes self * other.

source

fn div<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

source

fn bitand<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

Computes self & other.

source

fn bitor<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

Computes self | other.

source

fn bitxor<O>(&self, other: O) -> PyResult<Bound<'py, PyAny>>
where O: ToPyObject,

Computes self ^ other.

source

fn is_callable(&self) -> bool

Determines whether this object appears callable.

This is equivalent to Python’s callable() function.

§Examples
use pyo3::prelude::*;

Python::with_gil(|py| -> PyResult<()> {
    let builtins = PyModule::import_bound(py, "builtins")?;
    let print = builtins.getattr("print")?;
    assert!(print.is_callable());
    Ok(())
})?;

This is equivalent to the Python statement assert callable(print).

Note that unless an API needs to distinguish between callable and non-callable objects, there is no point in checking for callability. Instead, it is better to just do the call and handle potential exceptions.

source

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

Calls the object.

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

use pyo3::types::PyDict;

const CODE: &str = r#"
def function(*args, **kwargs):
    assert args == ("hello",)
    assert kwargs == {"cruel": "world"}
    return "called with args and kwargs"
"#;

Python::with_gil(|py| {
    let module = PyModule::from_code_bound(py, CODE, "", "")?;
    let fun = module.getattr("function")?;
    let args = ("hello",);
    let kwargs = PyDict::new_bound(py);
    kwargs.set_item("cruel", "world")?;

    let module = PyModule::import_bound(py, "builtins")?;
    let help = module.getattr("help")?;

    Ok(())
})?;

This is equivalent to the Python expression help().

source

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

Calls the object with only positional arguments.

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

§Examples

    assert args == ("hello",)
    assert kwargs == {}
    return "called with args"
"#;

Python::with_gil(|py| {
    let module = PyModule::from_code_bound(py, CODE, "", "")?;
    let fun = module.getattr("function")?;
    let args = ("hello",);
    let result = fun.call1(args)?;
    assert_eq!(result.extract::<String>()?, "called with args");
    Ok(())
})
source

fn call_method<N, A>( &self, name: N, args: A, kwargs: Option<&Bound<'_, PyDict>> ) -> PyResult<Bound<'py, PyAny>>
where N: IntoPy<Py<PyString>>, A: IntoPy<Py<PyTuple>>,

Calls a method on the object.

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern name.

§Examples
use pyo3::prelude::*;
use pyo3::types::PyDict;

const CODE: &str = r#"
class A:
    def method(self, *args, **kwargs):
        assert args == ("hello",)
        assert kwargs == {"cruel": "world"}
        return "called with args and kwargs"
a = A()
"#;

Python::with_gil(|py| {
    let module = PyModule::from_code_bound(py, CODE, "", "")?;
    let instance = module.getattr("a")?;
    let args = ("hello",);
    let kwargs = PyDict::new_bound(py);
    kwargs.set_item("cruel", "world")?;
    let result = instance.call_method("method", args, Some(&kwargs))?;
    assert_eq!(result.extract::<String>()?, "called with args and kwargs");
    Ok(())
})
source

fn call_method0<N>(&self, name: N) -> PyResult<Bound<'py, PyAny>>
where N: IntoPy<Py<PyString>>,

Calls a method on the object without arguments.

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern name.

        assert kwargs == {}
        return "called with no arguments"
a = A()
"#;

Python::with_gil(|py| {
    let module = PyModule::from_code_bound(py, CODE, "", "")?;
    let instance = module.getattr("a")?;
    let result = instance.call_method0("method")?;
    assert_eq!(result.extract::<String>()?, "called with no arguments");
    Ok(())
})
source

fn call_method1<N, A>(&self, name: N, args: A) -> PyResult<Bound<'py, PyAny>>
where N: IntoPy<Py<PyString>>, A: IntoPy<Py<PyTuple>>,

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

To avoid repeated temporary allocations of Python strings, the intern! macro can be used to intern name.

§Examples
use pyo3::prelude::*;

const CODE: &str = r#"
class A:
    def method(self, *args, **kwargs):

})
source

fn is_truthy(&self) -> PyResult<bool>

Returns whether the object is considered to be true.

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

Returns whether the object is Ellipsis, e.g. ....

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

source

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.

source

fn get_item<K>(&self, key: K) -> PyResult<Bound<'py, PyAny>>
where K: ToPyObject,

Gets an item from the collection.

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

source

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

Sets a collection item value.

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

source

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

Deletes an item from the collection.

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

source

fn iter(&self) -> PyResult<Bound<'py, 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.

source

fn get_type(&self) -> Bound<'py, PyType>

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

source

fn get_type_ptr(&self) -> *mut PyTypeObject

Returns the Python type pointer for this object.

source

fn downcast<T>(&self) -> Result<&Bound<'py, T>, DowncastError<'_, 'py>>
where T: PyTypeCheck,

Downcast this PyAny to a concrete Python type or pyclass.

Note that you can often avoid downcasting yourself by just specifying the desired type in function or method signatures. However, manual downcasting is sometimes necessary.

For extracting a Rust-only type, see PyAny::extract.

§Example: Downcasting to a specific Python object
use pyo3::prelude::*;
use pyo3::types::{PyDict, PyList};

Python::with_gil(|py| {
    let dict = PyDict::new_bound(py);
    assert!(dict.is_instance_of::<PyAny>());
    let any = dict.as_any();

    assert!(any.downcast::<PyDict>().is_ok());
    assert!(any.downcast::<PyList>().is_err());
});
§Example: Getting a reference to a pyclass

This is useful if you want to mutate a PyObject that might actually be a pyclass.

use pyo3::prelude::*;

#[pyclass]
struct Class {
    i: i32,
}

Python::with_gil(|py| {
    let class = Py::new(py, Class { i: 0 }).unwrap().into_bound(py).into_any();

    let class_bound: &Bound<'_, Class> = class.downcast()?;

    class_bound.borrow_mut().i += 1;

    // Alternatively you can get a `PyRefMut` directly
    let class_ref: PyRefMut<'_, Class> = class.extract()?;
    assert_eq!(class_ref.i, 1);
    Ok(())
})
source

fn downcast_into<T>(self) -> Result<Bound<'py, T>, DowncastIntoError<'py>>
where T: PyTypeCheck,

Like downcast but takes ownership of self.

In case of an error, it is possible to retrieve self again via DowncastIntoError::into_inner.

§Example
use pyo3::prelude::*;
use pyo3::types::{PyDict, PyList};

Python::with_gil(|py| {
    let obj: Bound<'_, PyAny> = PyDict::new_bound(py).into_any();

    let obj: Bound<'_, PyAny> = match obj.downcast_into::<PyList>() {
        Ok(_) => panic!("obj should not be a list"),
        Err(err) => err.into_inner(),
    };

    // obj is a dictionary
    assert!(obj.downcast_into::<PyDict>().is_ok());
})
source

fn downcast_exact<T>(&self) -> Result<&Bound<'py, T>, DowncastError<'_, 'py>>
where T: PyTypeInfo,

Downcast this PyAny to a concrete Python type or pyclass (but not a subclass of it).

It is almost always better to use PyAny::downcast because it accounts for Python subtyping. Use this method only when you do not want to allow subtypes.

The advantage of this method over PyAny::downcast is that it is faster. The implementation of downcast_exact uses the equivalent of the Python expression type(self) is T, whereas downcast uses isinstance(self, T).

For extracting a Rust-only type, see PyAny::extract.

§Example: Downcasting to a specific Python object but not a subtype
use pyo3::prelude::*;
use pyo3::types::{PyBool, PyLong};

Python::with_gil(|py| {
    let b = PyBool::new_bound(py, true);
    assert!(b.is_instance_of::<PyBool>());
    let any: &Bound<'_, PyAny> = b.as_any();

    // `bool` is a subtype of `int`, so `downcast` will accept a `bool` as an `int`
    // but `downcast_exact` will not.
    assert!(any.downcast::<PyLong>().is_ok());
    assert!(any.downcast_exact::<PyLong>().is_err());

    assert!(any.downcast_exact::<PyBool>().is_ok());
});
source

fn downcast_into_exact<T>(self) -> Result<Bound<'py, T>, DowncastIntoError<'py>>
where T: PyTypeInfo,

Like downcast_exact but takes ownership of self.

source

unsafe fn downcast_unchecked<T>(&self) -> &Bound<'py, T>

Converts this PyAny to a concrete Python type without checking validity.

§Safety

Callers must ensure that the type is valid or risk type confusion.

source

unsafe fn downcast_into_unchecked<T>(self) -> Bound<'py, T>

Like downcast_unchecked but takes ownership of self.

§Safety

Callers must ensure that the type is valid or risk type confusion.

source

fn extract<'a, T>(&'a self) -> PyResult<T>
where T: FromPyObjectBound<'a, 'py>,

Extracts some type from the Python object.

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

source

fn get_refcnt(&self) -> isize

Returns the reference count for the Python object.

source

fn repr(&self) -> PyResult<Bound<'py, PyString>>

Computes the “repr” representation of self.

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

source

fn str(&self) -> PyResult<Bound<'py, PyString>>

Computes the “str” representation of self.

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

source

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

Retrieves the hash code of self.

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

source

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

Returns the length of the sequence or mapping.

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

source

fn dir(&self) -> PyResult<Bound<'py, PyList>>

Returns the list of attributes of this object.

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

source

fn is_instance(&self, ty: &Bound<'py, PyAny>) -> PyResult<bool>

Checks whether this object is an instance of type ty.

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

source

fn is_exact_instance(&self, ty: &Bound<'py, PyAny>) -> bool

Checks whether this object is an instance of exactly type ty (not a subclass).

This is equivalent to the Python expression type(self) is ty.

source

fn is_instance_of<T: PyTypeInfo>(&self) -> bool

Checks whether this object is an instance of type T.

This is equivalent to the Python expression isinstance(self, T), if the type T is known at compile time.

source

fn is_exact_instance_of<T: PyTypeInfo>(&self) -> bool

Checks whether this object is an instance of exactly type T.

This is equivalent to the Python expression type(self) is T, if the type T is known at compile time.

source

fn contains<V>(&self, value: V) -> PyResult<bool>
where V: ToPyObject,

Determines if self contains value.

This is equivalent to the Python expression value in self.

source

fn py_super(&self) -> PyResult<Bound<'py, PySuper>>

Return a proxy object that delegates method calls to a parent or sibling class of type.

This is equivalent to the Python expression super()
