StreamRuleEngine

Struct StreamRuleEngine 

Source
pub struct StreamRuleEngine { /* private fields */ }
Expand description

Holds stream rule engine application-layer state or configuration. Use it with the documented coordinator methods; run, journal, event, provider, or port effects are called out on those methods rather than on construction.

Implementations§

Source§

impl StreamRuleEngine

Source

pub fn new(rules: Vec<StreamRule>) -> Result<Self, AgentError>

Creates a new application::stream value with explicit caller-provided inputs. This constructor is data-only and performs no I/O or external side effects.

Source

pub fn restore( rules: Vec<StreamRule>, state: StreamRuleEngineState, ) -> Result<Self, AgentError>

Builds the restore value. This is data construction and performs no I/O, journal append, event publication, or process work.

Source

pub fn rules(&self) -> &[StreamRule]

Returns the rules currently held by this value. This clones current stream-rule engine state for inspection without reading hidden payloads.

Source

pub fn snapshot_state(&self) -> StreamRuleEngineState

Returns the snapshot state currently held by this value. This clones current stream-rule engine state for inspection without reading hidden payloads.

Source

pub fn repeat_state_for( &self, rule: &StreamRule, ) -> StreamRuleRepeatStateSnapshot

Returns repeat state for derived from the supplied state. This uses only local coordinator state and performs no hidden host work.

Source

pub fn observe_delta( &mut self, delta: StreamDelta, ) -> Result<Vec<StreamIntervention>, AgentError>

Observe delta. This updates stream-rule repeat tracking from one observed delta and returns the resulting intervention.
