Module serialization 

Serialization module for converting external data formats to string values.

These functions convert data from external formats (JSON, MsgPack, Protobuf) into string values ready for use with ExecutionPlan::with_values().

• null values are skipped (treated as “fact not provided”)
• JSON numbers, booleans, arrays, objects are converted to their string representation

Example

use lemma::serialization::from_json;

let json = br#"{"discount": 21, "config": {"key": "value"}, "name": null}"#;
let values = from_json(json, &execution_plan)?;
// discount -> "21"
// config -> "{\"key\":\"value\"}"
// name -> skipped (null)
let plan = execution_plan.with_values(values, &limits)?;
