Struct SessionMetadata 

Source 
pub struct SessionMetadata {
    pub id: SessionId,
    pub start: i64,
    pub end: i64,
    pub emitted: bool,
}
Expand description

Metadata for a single session within a key’s session index.

Tracks the temporal bounds and emission state of a session. The accumulator state is stored separately under sac:<session_id>.

Fields§

§id: SessionId

Unique session identifier.

§start: i64

Session start timestamp (inclusive).

§end: i64

Session end timestamp (exclusive, = last event time + gap).

§emitted: bool

Whether this session has been emitted (used for retraction tracking).
