Struct Rule 

pub struct Rule {
    pub text: String,
    pub enabled: bool,
    pub confidence: Option<f64>,
    pub based_on_count: Option<u32>,
    pub id: Option<String>,
    pub sources: Vec<String>,
    pub created_at: Option<String>,
    pub retired_at: Option<String>,
    pub retired_reason: Option<String>,
}

One rule in a domain’s TOML file.

A rule outlives the pass that wrote it, so it carries its own lineage: id is what the validation ledger keys on, sources closes the provenance chain from a live rule back to the reflections it was argued from (batch-level — the learner’s per-rule attributions would be its own unverifiable testimony), and created_at is the staleness signal. Every new field defaults, so rule files written before they existed load unchanged — the same trick as Reflexion::origin, minus the fail-closed semantics, because absent lineage on an already-accepted rule is history, not a threat.

Fields

text: String

enabled: bool

confidence: Option<f64>

based_on_count: Option<u32>

id: Option<String>

Minted when the rule first enters the store; stable across consolidations that keep the text.

sources: Vec<String>

Reflexion ids of the batch that produced (or last rewrote) this rule.

created_at: Option<String>

retired_at: Option<String>

Set instead of deleting: a retired rule is evidence — the learner is told it was tried and measured harmful, which a deleted line cannot say — and the invalidation is reversible where erasure is not.

retired_reason: Option<String>

Implementations

impl Rule

pub fn active(&self) -> bool

Whether this rule rides in prompts. Retirement implies inactive even if enabled was left true by a hand edit — the stronger claim wins.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Rule

fn default() -> Self

A blank enabled rule — enabled: true mirrors the serde default, so ..Default::default() at a construction site cannot silently disable.

impl<'de> Deserialize<'de> for Rule

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Rule

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
