Struct TrajectoryView 

pub struct TrajectoryView<'a> { /* private fields */ }

Read-only lifetime-scoped view into the trajectory being built mid-run. Backed by the in-memory tail of the event stream. Distinct from TrajectoryHandle — the handle is a post-run reference used to load completed runs, TrajectoryView is a mid-run peek passed to critics.

Critics MUST NOT mutate the trajectory; this type enforces that by exposing only read accessors.

Implementations

impl<'a> TrajectoryView<'a>

pub fn new(events: &'a [Event]) -> Self

pub fn events(&self) -> &[Event]

pub fn turn_count(&self) -> u32

Count of completed turns in the view — one per turn.finished event.

pub fn to_handle(&self) -> TrajectoryHandle

Copy the view’s events into an in-memory TrajectoryHandle. Useful for critics / reflectors that want to pass the view downstream to an API that takes a handle (e.g., crate::TrajectoryHandle::in_memory via ReplayLlm).
