Struct PyContext 

pub struct PyContext(/* private fields */);

Represents a Python contextvars.Context object.

Values of this type are accessed via PyO3’s smart pointers, e.g. as Py<PyContext> or Bound<'py, PyContext>.

Implementations

impl PyContext

pub fn add_watcher( py: Python<'_>, callback: WatchCallback, ) -> PyResult<BoundContextWatcherGuard<'_>>

Registers a context watcher for the current interpreter.

Use watch_callback! to create the callback passed to this method. The returned BoundContextWatcherGuard removes the watcher when dropped; call BoundContextWatcherGuard::unbind if the watcher needs to outlive the current Python attachment.

Panics and returned PyErr values are reported as unraisable exceptions and never unwind across the C boundary.

const NAME: &'static str = "PyContext"

👎Deprecated since 0.28.0:

prefer using ::type_object(py).name() to get the correct runtime value

Class name.

const MODULE: Option<&'static str>

👎Deprecated since 0.28.0:

prefer using ::type_object(py).module() to get the correct runtime value

Module name, if any.

const TYPE_HINT: PyStaticExpr

Provides the full python type as a type hint.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn is_type_of(obj: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn type_object(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
