Struct LearningRecord 

pub struct LearningRecord {
    pub category: String,
    pub agent_id: String,
    pub branch_id: Option<String>,
    pub title: String,
    pub body: Value,
    pub timestamp: SystemTime,
}

One structured, emittable learning record — the single in-memory representation of a learning destined for the agent.learning wire variant.

The aggregator’s working-state entry types (StuckDurationEntry, RecoveryCycleEntry, ConflictEvent, and the permission counters) are projected into LearningRecords at flush time. The broker payload is then produced solely by From<&LearningRecord> for BrokerMessage — there is no parallel wire-record data model (the agent-learning-variant “Internal model serialises directly” requirement).

Fields

category: String

Open category tag (see the CATEGORY_* constants).

agent_id: String

Publishing agent id (typically LEARNINGS_AGENT_ID).

branch_id: Option<String>

Branch the record is scoped to; None for cross-cutting records (permission patterns, conflict pairs).

title: String

Short human-readable summary; mirrors the markdown bullet text.

body: Value

Category-specific structured body.

timestamp: SystemTime

When the record was committed; used for the hour bucket and the emitted ISO-8601 wire timestamp.

Implementations

impl LearningRecord

pub fn deterministic_id(&self) -> String

Computes the deterministic dedup id: a stable 16-hex-char (64-bit) hash of a canonical serialisation of category, branch_id, the body (object keys sorted), and the UTC hour bucket (YYYY-MM-DDTHH).

Uses the std-library DefaultHasher — no external crypto dependency. The id is not a security primitive; it only needs to be deterministic for the same canonical input so consumers can dedupe. Re-publishing the same logical record within one UTC hour yields the same id; across an hour boundary the id changes so a genuine recurrence registers.

Trait Implementations

impl Clone for LearningRecord

fn clone(&self) -> LearningRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LearningRecord

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

Formats the value using the given formatter.

impl From<&LearningRecord> for BrokerMessage

fn from(record: &LearningRecord) -> Self

Converts to this type from the input type.

impl PartialEq for LearningRecord

fn eq(&self, other: &LearningRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
