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.

autotrim_maxlen: Option<u32>

The approximate maximum number of entries to retain in each stream. Redis may retain slightly more entries than this value to improve trimming performance.

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 payload type names 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.
