Struct ExecutionStep 

pub struct ExecutionStep {
    pub id: u32,
    pub node_id: u32,
    pub context: Value,
    pub result: Option<Value>,
    pub error: Option<String>,
    pub iteration_index: Option<u32>,

}

Captures state at each evaluation step.

Fields

id: u32

Sequential step number

node_id: u32

ID of the node being evaluated

context: Value

Current context/scope data at this step

result: Option<Value>

Result after evaluating this node (None if error)

error: Option<String>

Error message if evaluation failed (None if success)

iteration_index: Option<u32>

Current iteration index (only for iterator body evaluations)

iteration_total: Option<u32>

Total iteration count (only for iterator body evaluations)
