Struct Rule 

pub struct Rule {
    pub id: String,
    pub when: Predicate,
    pub outcome: Outcome,
    pub description: Option<String>,
}

A flag’s targeting rule. Evaluated in declared order; first match wins.

The matching rule yields either:

• a fixed variant (e.g. "on"), or
• a rollout mapping subject → variant via sticky bucketing.

Fields

id: String

Stable identifier for telemetry.

when: Predicate

Predicate that must match for this rule to fire.

outcome: Outcome

Outcome when this rule fires.

description: Option<String>

Free-form description for operators.
