Struct EpisodeMetadata 

pub struct EpisodeMetadata {
    pub label: Option<String>,
    pub parent_episode: Option<SymbolId>,
    pub retracts: Vec<SymbolId>,
}

Agent-supplied Episode metadata. Passed into Store::commit_batch_with_metadata to attach a label / parent / retracts to the next committed Episode. See episode-semantics.md § 3.2 / § 4.2 / § 5.

Fields

label: Option<String>

Optional human-readable label.

parent_episode: Option<SymbolId>

Optional parent Episode.

retracts: Vec<SymbolId>

Episodes this Episode retracts.

Implementations

impl EpisodeMetadata

pub const MAX_LABEL_BYTES: usize = 256

Spec § 4.3 cap.

pub fn is_empty(&self) -> bool

True if no metadata is attached; the commit path skips emitting an EpisodeMeta record in this case.

Trait Implementations

impl Clone for EpisodeMetadata

fn clone(&self) -> EpisodeMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpisodeMetadata

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

Formats the value using the given formatter.

impl Default for EpisodeMetadata

fn default() -> EpisodeMetadata

Returns the “default value” for a type.

impl PartialEq for EpisodeMetadata

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