Evaluation context interface used by the AIMX engine.

Implementors provide:

• Reference lookup (get_value / set_value).
• Function and method dispatch via FunctionRegistry.
• Closure parameter stack management.
• Inference calls into workflows or closures.
• Imperative workflow execution via ContextLike::run_evaluation.

Required Methods

fn start_closure(&mut self) -> [(Arc<str>, Arc<Value>); 2]

Start a new closure and save the current stack.

fn set_key(&mut self, index: usize, identifier: Arc<str>)

Set the identifier of a closure parameter slot (0 or 1).

fn set_parameter(&mut self, index: usize, value: Arc<Value>)

Set the value of the index mapped parameter used by element-wise functions like map.

Arguments

• index - The index value to set (0 or 1)
• value - The value to set

fn end_closure(&mut self, stack: [(Arc<str>, Arc<Value>); 2])

End the closure and restore the previous stack.

fn get_value(&mut self, reference: &Reference) -> Result<Arc<Value>>

Get the value of a referenced rule or parameter variable.

Arguments

• reference - The reference to resolve

Returns

Returns the value of the referenced variable or an error if the reference cannot be resolved.

fn set_value(&mut self, identifier: &str, value: Arc<Value>) -> Result<()>

Set the value of a rule.

Arguments

• reference - The reference to the rule to set
• value - The value to assign

Returns

Returns Ok(()) on success or an error if the referenced rule cannot be set.

fn function_call( &mut self, name: Arc<str>, arg: Arc<Value>, ) -> Result<Arc<Value>>

Call a standalone function.

Arguments

• name - The name of the function to call
• arg - The argument(s) to pass to the function (Value can be Empty, Literal, or Array)

Returns

Returns the result of the function call or an error if the function is not found or if there’s an error during execution.

fn method_call( &mut self, name: Arc<str>, value: Arc<Value>, arg: Arc<Value>, ) -> Result<Arc<Value>>

Call a method on a value.

Arguments

• name - The name of the method to call
• value - The value on which to call the method
• arg - The argument(s) to pass to the method (Value can be Empty, Literal, or Array)

Returns

Returns the result of the method call or an error if the method is not found or if there’s an error during execution.

fn inference_call( &mut self, reference: Arc<Reference>, arg: Arc<Value>, ) -> Result<Arc<Value>>

Run inference on a referenced workflow.

Arguments

• reference - The workflow reference
• arg - The argument(s) to pass to the inference call (Value can be Empty, Literal, or Array)

Returns

Returns the result of the inference call or an error if the workflow is not found or if there’s an error during execution.

fn run_evaluation(&mut self, start_state: Option<Arc<str>>) -> WorkflowStatus
