Enum LogRecord 

pub enum LogRecord {
    Minted {
        manifest: Box<AttributionManifest>,
    },
    Mutation {
        token: Token,
        at: Timestamp,
        seq: Seq,
        change: Change,
    },
    Event(Event),
}

One record in the append-only log. A closed enum: new kinds are additive; folds ignore kinds they don’t know (doc 13 §4), which is what keeps the replay promise compatible across schema growth.

Variants

Minted

A token was born: the full manifest is the payload (doc 04 §1).

Fields

manifest: Box<AttributionManifest>

The manifest as minted (version == 1).

Mutation

A manifest’s mutable sections changed.

Fields

token: Token

The token whose manifest changed.

at: Timestamp

When.

seq: Seq

Per-token sequence (store-assigned; dedup key with token).

change: Change

What changed.

Event(Event)

A funnel event (payload-free — I-1).

Implementations

impl LogRecord

pub fn token(&self) -> Token

The token this record belongs to.

pub fn seq(&self) -> Seq

The per-token sequence. Minted is always seq 0 — birth precedes everything (the store assigns 1.. to subsequent records).
