FrontendAttachment

Struct FrontendAttachment

pub struct FrontendAttachment {
    pub descriptor: FrontendRuntimeDescriptor,
    pub history: Vec<ChatMessage>,
    pub history_cursor: u64,
    /* private fields */
}

Expand description

Atomic history/replay/live attachment to one runtime.

Fields§

§descriptor: FrontendRuntimeDescriptor

Runtime description captured at attachment time.

§history: Vec<ChatMessage>

Bounded canonical history through history_cursor.

§history_cursor: u64

Highest event sequence already represented by history.

Implementations§

impl FrontendAttachment

pub fn from_snapshot( snapshot: FrontendAttachSnapshot, live: Receiver<SdkEvent>, ) -> FrontendAttachment

Build an in-process attachment from a serialized snapshot and a live SDK event receiver. Runtime adapters use this constructor in tests and protocol bridges without acquiring transport ownership.

pub fn from_snapshot_after( snapshot: FrontendAttachSnapshot, live: Receiver<SdkEvent>, acknowledged_sequence: u64, ) -> FrontendAttachment

Build an attachment that resumes after a sequence acknowledged by a prior transport connection. Snapshot replay and any overlapping live events at or below the cursor are skipped without changing canonical history or event payloads.

pub async fn next_event(&mut self) -> Result<SdkEvent, SdkError>

Receive the next event not already represented by the history or a prior replay item. Duplicate events queued during attachment are skipped by sequence.

pub fn next_replay_event(&mut self) -> Option<SdkEvent>

Drain one event from the finite attachment replay without waiting for live input. Interactive frontends use this to project the complete atomic snapshot before accepting keystrokes, so a historical resolved request never appears transiently actionable.
