Configuration for MessageBus instances.

Fields

encoding: SerializationEncoding

The default encoding for externally published payloads.

encoding_market_data: Option<SerializationEncoding>

The encoding for market data payloads supported by the external bus binary codecs.

encoding_builtin: Option<SerializationEncoding>

The encoding for built-in account, portfolio, order, and position payloads.

timestamps_as_iso8601: bool

If timestamps should be persisted as ISO 8601 strings. If false, then timestamps will be persisted as UNIX nanoseconds.

buffer_interval_ms: Option<u32>

The buffer interval (milliseconds) between pipelined/batched transactions. The recommended range if using buffered pipelining is [10, 1000] milliseconds, with a good compromise being 100 milliseconds.

autotrim_mins: Option<u32>

The lookback window in minutes for automatic stream trimming. The actual window may extend up to one minute beyond the specified value since streams are trimmed at most once every minute. This feature requires Redis version 6.2 or higher; otherwise, it will result in a command syntax error.

use_trader_prefix: bool

If a ‘trader-’ prefix is used for stream names.

use_trader_id: bool

If the trader’s ID is used for stream names.

use_instance_id: bool

If the trader’s instance ID is used for stream names. Default is false.

streams_prefix: String

The prefix for externally published stream names.

stream_per_topic: bool

If true, messages will be written to separate streams per topic. If false, all messages will be written to the same stream.

external_streams: Option<Vec<String>>

The external stream keys the message bus will listen to for publishing deserialized message payloads internally.

types_filter: Option<Vec<String>>

A list of serializable types not to publish externally.

heartbeat_interval_secs: Option<u16>

The heartbeat interval (seconds).

Implementations

impl MessageBusConfig

pub fn builder() -> MessageBusConfigBuilder

Create an instance of MessageBusConfig using the builder syntax

impl MessageBusConfig

pub fn validate(&self) -> ConfigResult<()>

Validates external message bus encoding policy.

Errors

Returns a ConfigError when the default encoding cannot carry custom payloads, or when a category override selects an encoding unsupported by any payload type in that category.

Trait Implementations

impl Clone for MessageBusConfig

fn clone(&self) -> MessageBusConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageBusConfig

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

Formats the value using the given formatter.

impl Default for MessageBusConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MessageBusConfig

where MessageBusConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MessageBusConfig

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

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 MessageBusConfig

fn eq(&self, other: &MessageBusConfig) -> 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 MessageBusConfig

const NAME: &str = "MessageBusConfig"

Name of the class.

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for MessageBusConfig

const MODULE: Option<&str>

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

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForMessageBusConfig

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

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

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.
