Struct zen_engine::DecisionEngine

pub struct DecisionEngine<L>where
    L: DecisionLoader,{ /* private fields */ }

Structure used for generating and evaluating JDM decisions

Implementations

pub fn new_arc(loader: Arc<L>) -> Self

pub async fn evaluate<K>( &self, key: K, context: &Value ) -> Result<DecisionGraphResponse, Box<EvaluationError>>where K: AsRef<str>,

Evaluates a decision through loader using a key

pub async fn evaluate_with_opts<K>( &self, key: K, context: &Value, options: EvaluationOptions ) -> Result<DecisionGraphResponse, Box<EvaluationError>>where K: AsRef<str>,

Evaluates a decision through loader using a key with advanced options

pub fn create_decision(&self, content: Arc<DecisionContent>) -> Decision<L>

Creates a decision from DecisionContent, exists for easier binding creation

pub async fn get_decision(&self, key: &str) -> LoaderResult<Decision<L>>

Retrieves a decision based on the loader
