Struct EpisodeMetaRecord 

pub struct EpisodeMetaRecord {
    pub episode_id: SymbolId,
    pub at: ClockTime,
    pub label: Option<String>,
    pub parent_episode_id: Option<SymbolId>,
    pub retracts: Vec<SymbolId>,
}

Episode metadata record — extends the mechanical Checkpoint with the agent-visible fields from episode-semantics.md § 4.2 that the bare Checkpoint doesn’t carry: optional label, optional parent Episode link, and a (possibly empty) list of retracted Episodes.

Emitted by the store immediately before the batch’s Checkpoint. Batches that don’t carry an (episode :start ...) form have no EpisodeMeta.

Fields

episode_id: SymbolId

Episode ID this metadata describes (same as the following Checkpoint’s episode_id).

at: ClockTime

Commit time — same as the Checkpoint’s at.

label: Option<String>

Optional human-readable label. Capped at 256 bytes per episode-semantics.md § 4.3.

parent_episode_id: Option<SymbolId>

Optional parent Episode.

retracts: Vec<SymbolId>

Episodes this Episode retracts.

Trait Implementations

impl Clone for EpisodeMetaRecord

fn clone(&self) -> EpisodeMetaRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpisodeMetaRecord

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

Formats the value using the given formatter.

impl PartialEq for EpisodeMetaRecord

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