Struct SessionView 

pub struct SessionView {
    pub turns: BTreeMap<u32, Turn>,
    pub request_to_turn: HashMap<u32, u32>,
    /* private fields */
}

Client-side view of a session’s turn history.

Maps turn_id → Turn (ordered) and request_id → turn_id for routing streaming chunks during an active agent loop.

Fields

turns: BTreeMap<u32, Turn>

turn_id → Turn. Ordered by key (monotonically assigned by daemon).

request_to_turn: HashMap<u32, u32>

request_id → turn_id for streaming chunk routing. Inserted on Started, removed on Done/Failed/Cancelled.

Implementations

impl SessionView

pub fn new() -> Self

pub fn insert_or_replace(&mut self, turn_id: u32, turn: Turn)

pub fn clear_tool_call_descriptions(&mut self, turn_id: u32)

Drop the invocation-description entries for every call of turn_id.

Self::insert_or_replace cleans the map when the authoritative turn replaces the accumulated one, but a request that fails mid-tool never re-broadcasts its turn (Failed arrives with no final TurnAppended), and a success whose final broadcast was dropped under load would otherwise leak entries too. Callers invoke this from their request-terminal handlers (handle_done / handle_failed) so the map stays bounded by in-flight calls even on those paths.

pub fn get(&self, turn_id: u32) -> Option<&Turn>

pub fn get_mut(&mut self, turn_id: u32) -> Option<&mut Turn>

pub fn request_turn(&self, request_id: u32) -> Option<&Turn>

pub fn request_turn_mut(&mut self, request_id: u32) -> Option<&mut Turn>

pub fn stream_chunk( &mut self, request_id: u32, stream: &OutputStream, data: &str, )

Route streaming output to the current turn for this request.

pub fn tool_call_started( &mut self, request_id: u32, call_id: String, name: String, args: String, invocation_description: &str, )

Route a tool call start notification.

pub fn tool_result_chunk(&mut self, request_id: u32, call_id: &str, data: &str)

Route a tool result chunk — appends to the matching ToolResultRecord. Creates a stub record if the ToolCallStarted event hasn’t arrived yet.

pub fn iter(&self) -> impl Iterator<Item = (&u32, &Turn)>
