Clarification on terminology and rule conditions

[joyrexus]

Wondering about the distinction between a Rule and a Condition .. and whether there's really any need to have these two distinct types?

Let me explain.

So, RulePilot distinguishes between the following things ...

• Rule - a collection of conditions (with an optional default result)
• Condition - a boolean operator (any|all|none) operating on one or more conditions or constraints (with optional result)
• Constraint - a data test expression checking if operator(field, value) is true or false

A rule can have one or more "conditions":

// a single condition rule
const rule1: Rule = {
  conditions: { ... },
};

// another single condition rule
const rule2: Rule = {
  conditions: [{ ... }],
};

// a rule with two conditions
const rule3: Rule = {
  conditions: [{ ... }, { ... }],
};

// a rule with two conditions and a default result
const rule4: Rule = {
  conditions: [{ ... }, { ... }],
  default: "DEFAULT",
};

What's not immediately clear is why you need to distinguish between a Rule and a Condition at all.

A rule with two conditions seems equivalent to an any condition with the same two original conditions in its array.

Can you clarify what motivated the distinction?
