Crate nautilus_persistence_macros 

Procedural macros for Nautilus. Provides #[custom_data] for defining custom data types with generated boilerplate (constructor, HasTsInit, CustomDataTrait, Arrow, derives).

Attribute Macros

custom_data

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>.
