Struct McpStreamEvent 

Source 
pub struct McpStreamEvent {
    pub id: u64,
    pub event: McpEventKind,
    pub data: Value,
}
Expand description

One event on a session’s SSE stream. Cloneable so the broadcast channel can fan out one event to N concurrent subscribers.

The id is monotonic per session — clients carry the last seen id in a Last-Event-ID header on reconnect to request a replay of missed events. Heartbeats CARRY ids too (no second id space) so a reconnecting client never sees a gap.

Fields§

§id: u64

Monotonic per-session event id. First event is 1 (the init event); 0 is reserved as the sentinel “I have never seen anything” value clients send on first connect.

§event: McpEventKind

Wire-event discriminator (init / message / progress / lagged / heartbeat).

§data: Value

JSON payload. For message / progress this is the full JSON-RPC envelope minus the transport id. For init / lagged / heartbeat it’s an event-specific Solo-shaped object documented at each call site.
