Struct EvaluateDecisionRequest 

pub struct EvaluateDecisionRequest<T: EvaluateDecisionRequestState> { /* private fields */ }

Request to evaluate a DMN decision

The decision to evaluate can be specified either by using its unique key (as returned by DeployResource), or using the decision ID. When using the decision ID, the latest deployed version of the decision is used.

Examples

client
    .evaluate_decision()
    .with_decision_key(123456)
    .with_decision_id(String::from("decision_id"))
    .send()
    .await?;

Implementations

impl EvaluateDecisionRequest<Initial>

pub fn with_decision_key( self, decision_key: i64, ) -> EvaluateDecisionRequest<WithKey>

Sets the unique key of the decision to evaluate

Arguments

• decision_key - The unique key identifying the decision (as returned by DeployResource)

Returns

The updated EvaluateDecisionRequest in the WithKey state.

impl EvaluateDecisionRequest<WithKey>

pub fn with_decision_id( self, decision_id: String, ) -> EvaluateDecisionRequest<WithId>

Sets the ID of the decision to evaluate

Arguments

• decision_id - The ID of the decision to evaluate

Returns

The updated EvaluateDecisionRequest in the WithId state.

impl EvaluateDecisionRequest<WithId>

pub fn with_variables<T: Serialize>(self, data: T) -> Result<Self, ClientError>

Sets the variables used for decision evaluation

The variables must be a JSON object, as variables will be mapped in a key-value fashion. For example: { "a": 1, "b": 2 } will create two variables named “a” and “b”.

Arguments

• data - The variables to be used for decision evaluation

Returns

The updated EvaluateDecisionRequest with the variables set.

Errors

Returns a ClientError if the variables cannot be serialized to JSON.

pub async fn send<T: DeserializeOwned>( self, ) -> Result<EvaluateDecisionResponse<T>, ClientError>

Sends the decision evaluation request

Type Parameters

• T - The type of the decision output

Returns

A Result containing the EvaluateDecisionResponse or a ClientError.

pub fn with_tenant_id(self, tenant_id: String) -> Self

Sets the tenant ID for the decision evaluation

Arguments

• tenant_id - The ID of the tenant that owns the decision

Returns

The updated EvaluateDecisionRequest with the tenant ID set.
