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

Required Methods

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.

Errors

Returns an error if JSON serialization fails.

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.

Provided Methods

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.

Errors

Returns an error if JSON serialization fails.

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

Converts the custom data to a Python object.

Errors

Returns an error if PyO3 conversion fails.

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.

Errors

Returns an error if JSON deserialization fails.
