Resolved Nautilus instrument ID when the coin is known in cache.

price: Decimal

Fill price.

size: Decimal

Fill size.

side: OrderSide

Fill side.

hash: String

L1 transaction hash.

oid: u64

Venue order id for the slice.

tid: u64

Venue trade id.

crossed: bool

Whether the fill crossed the spread (taker).

fee: Decimal

Fee amount (negative means rebate).

fee_token: String

Token the fee was paid in.

dir: String

Frontend display direction string from the venue.

closed_pnl: Decimal

Closed PnL for the fill.

is_snapshot: bool

Whether this event belongs to a venue snapshot batch.

ts_event: UnixNanos

UNIX timestamp (nanoseconds) when the fill occurred.

ts_init: UnixNanos

UNIX timestamp (nanoseconds) when the instance was initialized.

Implementations

impl HyperliquidTwapSliceFill

pub fn new( user: String, twap_id: u64, coin: String, instrument_id: Option<InstrumentId>, price: Decimal, size: Decimal, side: OrderSide, hash: String, oid: u64, tid: u64, crossed: bool, fee: Decimal, fee_token: String, dir: String, closed_pnl: Decimal, is_snapshot: bool, ts_event: UnixNanos, ts_init: UnixNanos, ) -> Self

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

impl HyperliquidTwapSliceFill

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 HyperliquidTwapSliceFill

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 HyperliquidTwapSliceFill

fn path_prefix() -> &'static str

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

impl Clone for HyperliquidTwapSliceFill

fn clone(&self) -> HyperliquidTwapSliceFill

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomDataSerialize for HyperliquidTwapSliceFill

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 HyperliquidTwapSliceFill

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

Returns the event timestamp (when the data occurred).
