Struct ArrayTrajectory 

pub struct ArrayTrajectory { /* private fields */ }

Eager trajectory: all models held in memory.

All frames must share the same Arc<AtomicHierarchy> (verified on construction). This invariant ensures that topology does not vary across frames, which is required for correct trajectory analysis.

Implementations

impl ArrayTrajectory

pub fn new(models: Vec<Model>) -> Result<Self, TrajectoryError>

Construct from a Vec<Model>.

Returns Err(TrajectoryError::Empty) if models is empty. Returns Err(TrajectoryError::MixedTopologies) if any two models have different Arc<AtomicHierarchy> pointers.

pub fn models(&self) -> &[Model]

Returns a slice of all models in the trajectory.

Trait Implementations

impl Trajectory for ArrayTrajectory

fn frame_count(&self) -> usize

Total number of frames in the trajectory.

fn representative(&self) -> &Model

A representative frame (typically the first), useful when callers need topology access without specifying a frame index.

fn frame(&self, index: usize) -> Cow<'_, Model>

Returns the frame at index, either borrowed or constructed on demand.
