Implementations

impl RustTestTypedMapCustomData

pub fn new( name: String, instrument_ids: IndexMap<String, InstrumentId>, account_ids: IndexMap<String, AccountId>, currencies: IndexMap<String, Currency>, bar_types: IndexMap<String, BarType>, prices: IndexMap<String, Price>, quantities: IndexMap<String, Quantity>, monies: IndexMap<String, Money>, prices_by_instrument: IndexMap<InstrumentId, Price>, quantities_by_account: IndexMap<AccountId, Quantity>, monies_by_currency: IndexMap<Currency, Money>, prices_by_bar_type: IndexMap<BarType, Price>, hash_prices_by_instrument: HashMap<InstrumentId, Price>, strings: HashMap<String, String>, floats_64: HashMap<String, f64>, floats_32: HashMap<String, f32>, booleans: HashMap<String, bool>, integers_u64: HashMap<String, u64>, integers_i64: HashMap<String, i64>, integers_u32: HashMap<String, u32>, integers_i32: HashMap<String, i32>, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self

Constructor from all fields. Use from Rust; Python init forwards to this.

impl RustTestTypedMapCustomData

pub fn repr(&self) -> String

Returns a string representation in the same style as Python CustomDataClass (fields and ts_event/ts_init as ISO8601).

Trait Implementations

impl ArrowSchemaProvider for RustTestTypedMapCustomData

fn get_schema(metadata: Option<HashMap<String, String>>) -> Schema

Returns the Arrow schema for this type with optional metadata.

fn get_schema_map() -> HashMap<String, String>

Returns a map of field names to their Arrow data types.

impl CatalogPathPrefix for RustTestTypedMapCustomData

fn path_prefix() -> &'static str

Returns the path prefix (directory name) for this data type.

impl Clone for RustTestTypedMapCustomData

fn clone(&self) -> RustTestTypedMapCustomData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomDataSerialize for RustTestTypedMapCustomData

fn schema(&self) -> Result<Schema>

Returns the Arrow schema for this custom data type.

fn encode_record_batch( &self, items: &[Arc<dyn CustomDataTrait>], ) -> Result<RecordBatch>

Encodes a batch of custom data items to an Arrow RecordBatch.

impl CustomDataTrait for RustTestTypedMapCustomData

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

Returns the type name for the custom data.

fn type_name_static() -> &'static str

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

fn as_any(&self) -> &dyn Any

Returns the data as a dyn Any for downcasting.

fn ts_event(&self) -> UnixNanos
