Configuration for live data engines.

Fields

time_bars_build_with_no_updates: bool

If time bar aggregators will build and emit bars with no new market updates.

time_bars_timestamp_on_close: bool

If time bar aggregators will timestamp ts_event on bar close. If false, the aggregator will timestamp on bar open.

time_bars_skip_first_non_full_bar: bool

If time bar aggregators will skip emitting a bar when aggregation starts mid-interval.

time_bars_interval_type: BarIntervalType

The interval semantics used for time aggregation.

time_bars_build_delay: u64

The build delay (microseconds) before a time bar is emitted.

time_bars_origins: HashMap<String, u64>

A mapping of time bar aggregation types to their origin time offsets (nanoseconds).

Keys are BarAggregation variant names, values are offset durations in nanoseconds.

validate_data_sequence: bool

If data timestamp sequencing should be validated and handled.

buffer_deltas: bool

If order book deltas should be buffered until the F_LAST flag is set for a delta.

emit_quotes_from_book: bool

If quotes should be emitted on order book updates.

emit_quotes_from_book_depths: bool

If quotes should be emitted on order book depth updates.

external_clients: Option<Vec<ClientId>>

Client IDs declared for external stream processing.

The data engine will not attempt to send data commands to these client IDs.

debug: bool

If debug mode is active (will provide extra debug logging).

graceful_shutdown_on_error: bool

If the engine should gracefully shut down when queue processing encounters unexpected errors.

qsize: u32

The queue size for the engine’s internal queue buffers.

Not implemented on the current live runtime; validate_runtime_support rejects any value other than the default.

Implementations

impl LiveDataEngineConfig

pub fn builder() -> LiveDataEngineConfigBuilder

Create an instance of LiveDataEngineConfig using the builder syntax

Trait Implementations

impl Clone for LiveDataEngineConfig

fn clone(&self) -> LiveDataEngineConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiveDataEngineConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LiveDataEngineConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LiveDataEngineConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<LiveDataEngineConfig> for DataEngineConfig

fn from(config: LiveDataEngineConfig) -> Self

Converts to this type from the input type.

impl<'a, 'py> FromPyObject<'a, 'py> for LiveDataEngineConfig

where Self: Clone,

type Error = PyClassGuardError<'a, 'py>

The type returned in the event of a conversion error.

fn extract( obj: Borrowed<'a, 'py, PyAny>, ) -> Result<Self, <Self as FromPyObject<'a, 'py>>::Error>

Extracts Self from the bound smart pointer obj.

impl<'py> IntoPyObject<'py> for LiveDataEngineConfig

type Target = LiveDataEngineConfig

The Python output type

type Output = Bound<'py, <LiveDataEngineConfig as IntoPyObject<'py>>::Target>

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for LiveDataEngineConfig

fn eq(&self, other: &LiveDataEngineConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for LiveDataEngineConfig

const NAME: &str = "LiveDataEngineConfig"

Name of the class.

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for LiveDataEngineConfig

const MODULE: Option<&str>

type Layout = <<LiveDataEngineConfig as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<LiveDataEngineConfig>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
