Module custom 

Structs

CustomData

A wrapper for custom data including its data type.

PythonCustomDataWrapper

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

Traits

CustomDataTrait

Trait for typed custom data that can be used within the Nautilus domain model.

Functions

clone_pyclass_to_pyobject

Converts a cloneable PyO3-backed custom data value into a Python object.

ensure_custom_data_json_registered

Registers a custom data type for JSON deserialization if not already registered. Idempotent: safe to call multiple times for the same type (e.g. module init).

get_python_data_class

reconstruct_python_custom_data

Reconstructs a Python custom data instance from type name and JSON.

register_custom_data_json

Registers a custom data type for JSON deserialization. When Data::deserialize sees the type name returned by T::type_name_static(), it will call T::from_json.
