Struct ParticleTrajectory 

pub struct ParticleTrajectory {
    pub frames: Vec<ParticleDataset>,
    pub title: String,
}

A multi-frame particle trajectory storing all time steps in memory.

Fields

frames: Vec<ParticleDataset>

All snapshots in time order.

title: String

Simulation title / description.

Implementations

impl ParticleTrajectory

pub fn new(title: impl Into<String>) -> Self

Create an empty trajectory.

pub fn push(&mut self, ds: ParticleDataset)

Append a frame.

pub fn num_frames(&self) -> usize

Number of frames.

pub fn time_span(&self) -> Option<(f64, f64)>

Time span (t_start, t_end), or None if empty.

pub fn frame_at(&self, t: f64) -> Option<&ParticleDataset>

Return the frame closest to a given time.

pub fn kinetic_energy_series(&self) -> Vec<(f64, f64)>

Compute kinetic energy over time as (time, energy) pairs.
