#[custom_data]Expand description
Expands a struct into a custom data type with generated impls: #[derive(Debug, Clone, Serialize, Deserialize, PartialEq)], constructor, HasTsInit, CustomDataTrait,
ArrowSchemaProvider, EncodeToRecordBatch, DecodeDataFromRecordBatch,
CatalogPathPrefix, From/TryFrom for Data. Call nautilus_serialization::ensure_custom_data_registered::<T>()
and (for Python) nautilus_model::data::register_rust_extractor::<T>() once per type.
Requires fields to include ts_event and ts_init (e.g. nautilus_core::UnixNanos).
Supported field types include InstrumentId, AccountId, Currency, BarType, Params, UnixNanos,
f64, f32, bool, String, u64, i64, u32, i32, Vec<f64>, and Vec<u8>.
Use #[custom_data(pyo3)] or #[custom_data(python)] to also generate Python bindings:
#[cfg_attr(feature = "python", pyo3::pyclass)] on the struct and a #[pymethods] impl with
#[new] constructor and #[getter] per field. When pyo3 is set, the Rust constructor is
named new; Python __init__ forwards to it.
Use #[custom_data(pyo3, no_display)] to skip generating repr() and Display so you can implement them manually.
