Struct SessionSummaryChangedParams 

pub struct SessionSummaryChangedParams {
    pub channel: Uri,
    pub session: Uri,
    pub changes: PartialSessionSummary,
}

Broadcast to all clients subscribed to the root channel when an existing session’s summary changes (title, status, modifiedAt, model, working directory, read/done state, or diff statistics).

This notification lets clients that maintain a cached session list — for example, the result of a previous listSessions() call — stay in sync with in-flight sessions without having to subscribe to every session URI individually. It is complementary to, not a replacement for, root/sessionAdded and root/sessionRemoved: those signal lifecycle (creation/disposal), while this signals summary-level mutations on an already-known session.

Semantics:

• Only fields present in changes have new values; omitted fields are unchanged on the client’s cached summary.
• Identity fields (resource, provider, createdAt) never change and are not carried.
• Like all protocol notifications, this is ephemeral: it is not replayed on reconnect. On reconnect, clients should re-fetch the full catalog via listSessions() as usual.
• The server SHOULD emit this notification whenever any mutable field on {@link SessionSummary | SessionSummary} changes for a session the server has surfaced via listSessions() or root/sessionAdded. Servers MAY coalesce or debounce updates for noisy fields (for example, modifiedAt bumps while a turn is streaming) at their discretion.
• Clients that have no cached entry for session MAY ignore the notification; it is not a substitute for root/sessionAdded.

Fields

channel: Uri

Channel URI this notification belongs to (the root channel)

session: Uri

URI of the session whose summary changed

changes: PartialSessionSummary

Mutable summary fields that changed; omitted fields are unchanged.

Identity fields (resource, provider, createdAt) never change and MUST be omitted by senders; receivers SHOULD ignore them if present.

Trait Implementations

impl Clone for SessionSummaryChangedParams

fn clone(&self) -> SessionSummaryChangedParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionSummaryChangedParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionSummaryChangedParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SessionSummaryChangedParams

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

impl Serialize for SessionSummaryChangedParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
