# convertRuleStructToString

> **convertRuleStructToString**(`functionString`, `encodedValues`, `ruleS`, `plhArray`, `foreignCalls`, `trackers`, `mappings`): [`RuleJSON`](../../../modules/validation/interfaces/RuleJSON)

Converts a `RuleStruct` object into a JSON-like string representation.

## Parameters

| `mappings`       | [`hexToFunctionString`](../../../modules/types/type-aliases/hexToFunctionString)\[] | An array of mappings that associate a `hex` signature with a function.                                        |

## Returns

[`RuleJSON`](../../../modules/validation/interfaces/RuleJSON)

An object of type `ruleJSON` containing the condition, positive effects, negative effects, calling function, and encoded values.

The function processes the `RuleStruct` object to:

* Extract placeholder names and append them to `plhArray`.
* Parse and format positive and negative effects into strings.
* Reverse parse the rule's instruction set to generate a condition string.
* Populate the `ruleJSON` object with the processed data.
