Enum FrameKind 

pub enum FrameKind {
    Rows = 0,
    Ddl = 1,
    Empty = 2,
}

The entry kind — today’s _rindle_change_log.kind discriminator plus the shapes the journal substrate adds.

Variants

Rows = 0

Row deltas: the payload contains ordered flat-change chunks.

Ddl = 1

A schema change riding the log in-band (RELAY-DDL-DESIGN.md): replay mutates the schema at exactly this offset. DDL entries are fold barriers (212 §4.2) and the reason no frame ever meets the wrong schema epoch (212 §3.1).

Empty = 2

An empty entry with no payload: the engine itself writes empty journal records on post-allocation validation failure, and zero-fills crash gaps at reopen (211 §4). They ship as empty frames so cid contiguity is preserved end-to-end (212 §2.1). committed_at is 0 (unknown) — the engine’s records carry no wall clock.

Trait Implementations

impl Clone for FrameKind

fn clone(&self) -> FrameKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameKind

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

Formats the value using the given formatter.

impl PartialEq for FrameKind

fn eq(&self, other: &FrameKind) -> 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.
