STRUCT

# rule\_parameters

Used to simplify rule creation, it describes a rule without the operator.

This struct shouldn't generally be handled by developers, the intended workflow is
`less_than(block_height(10));`, which should give a `rule_expression` without ever
handling `rule_parameters`

```signature
struct rule_parameters {
 variable: rule_variable;
 value: integer;
}
```

`variable: rule_variable;`
:   The variable of the rule

`value: integer;`
:   The value to check against
