Struct PythonCustomDataWrapper 

pub struct PythonCustomDataWrapper { /* private fields */ }

Wraps a Python custom data object so it can participate in the Rust data pipeline as an Arc<dyn CustomDataTrait>.

Holds a reference to the Python object and delegates trait methods via the Python GIL. ts_event, ts_init, and type_name are cached at construction to avoid GIL acquisition in the hot path (e.g., data sorting, message routing).

Implementations

impl PythonCustomDataWrapper

pub fn new(_py: Python<'_>, py_object: &Bound<'_, PyAny>) -> PyResult<Self>

Creates a new wrapper from a Python custom data object.

Extracts and caches ts_event, ts_init, and the type name from the Python object.

Errors

Returns an error if required attributes cannot be extracted from the Python object.

pub fn py_object(&self) -> &Py<PyAny>

Returns a reference to the underlying Python object.

pub fn get_type_name(&self) -> &str

Returns the cached type name.

Trait Implementations

impl Clone for PythonCustomDataWrapper

Available on crate feature python only.

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CustomDataTrait for PythonCustomDataWrapper

Available on crate feature python only.

fn type_name(&self) -> &'static str

Returns the type name for the custom data.

fn as_any(&self) -> &dyn Any

Returns the data as a dyn Any for downcasting.

fn ts_event(&self) -> UnixNanos

Returns the event timestamp (when the data occurred).

fn to_json(&self) -> Result<String>

Serializes the custom data to a JSON string.

fn clone_arc(&self) -> Arc<dyn CustomDataTrait>

Returns a cloned Arc of the custom data.

fn eq_arc(&self, other: &dyn CustomDataTrait) -> bool

Returns whether the custom data is equal to another.

fn to_pyobject(&self, py: Python<'_>) -> PyResult<Py<PyAny>>

Converts the custom data to a Python object.

fn to_json_py(&self) -> Result<String>

Python-facing JSON serialization. Default implementation forwards to to_json. Override if a different behavior is needed for the Python API.

fn type_name_static() -> &'static str

where Self: Sized,

Returns the type name used in serialized form (e.g. in the "type" field).

fn from_json(_value: Value) -> Result<Arc<dyn CustomDataTrait>>

where Self: Sized,

Deserializes from a JSON value into an Arc’d trait object.

impl Debug for PythonCustomDataWrapper

Available on crate feature python only.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasTsInit for PythonCustomDataWrapper

Available on crate feature python only.

fn ts_init(&self) -> UnixNanos

Returns the UNIX timestamp (nanoseconds) when the instance was created.
