Struct HistoryPage 

#[non_exhaustive]
pub struct HistoryPage {
    pub session_id: SessionId,
    pub messages: Vec<SessionMessage>,
    pub next_cursor: Option<HistoryCursor>,
}

One bounded page of a session conversation.

Messages are ordered oldest-first by canonical event sequence. A page never implies that the complete history was loaded: continue with next_cursor when it is present.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

session_id: SessionId

The session this page belongs to.

messages: Vec<SessionMessage>

Messages in canonical event-sequence order, oldest first.

next_cursor: Option<HistoryCursor>

Opaque continuation cursor, or None when the snapshot is exhausted.
