Expand description

CRDT projection for session state.

This is a materialized view derived from applying events. Supports CRDT merge for conflict resolution.

Fields§

§session_key: SessionKey

Session identifier.

§agent_id: String

Agent ID.

§channel: ChannelId

Channel.

§peer_id: String

Peer ID.

§state: SessionState

Current state.

§message_count: u64

Total message count.

§last_activity: DateTime<Utc>

Last activity timestamp.

§messages: Vec<SessionMessage>

Message history.

§custom_state: HashMap<String, Value>

Custom state key-value pairs.

§last_event_id: Option<EventId>

Last event ID applied.

Implementations§

impl SessionProjection

pub fn new( session_key: SessionKey, agent_id: String, channel: ChannelId, peer_id: String, ) -> Self

Create a new empty projection.

pub fn apply(&mut self, event: &SessionEvent)

Apply an event to update the projection.

pub fn merge(&mut self, other: &Self)

CRDT merge with another projection.

Uses last-write-wins for scalar fields, union for messages.
