Struct SimulationState 

pub struct SimulationState {
    pub positions: Vec<[f64; 3]>,
    pub velocities: Vec<[f64; 3]>,
    pub forces: Vec<[f64; 3]>,
    pub metadata: HashMap<String, f64>,
}

Full simulation snapshot: positions, velocities, forces, and metadata.

Fields

positions: Vec<[f64; 3]>

Particle positions [x, y, z].

velocities: Vec<[f64; 3]>

Particle velocities [vx, vy, vz].

forces: Vec<[f64; 3]>

Per-particle forces [fx, fy, fz].

metadata: HashMap<String, f64>

Arbitrary scalar metadata keyed by name.

Implementations

impl SimulationState

pub fn new() -> Self

Create an empty SimulationState.

pub fn len(&self) -> usize

Number of particles in this state.

pub fn is_empty(&self) -> bool

Return true if there are no particles.

pub fn to_bytes(&self) -> Vec<u8>

Serialise to a flat byte buffer (positions + velocities + forces).

pub fn from_bytes(data: &[u8]) -> Result<Self>

Deserialise from a flat byte buffer.

Trait Implementations

impl Clone for SimulationState

fn clone(&self) -> SimulationState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SimulationState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SimulationState

fn default() -> Self

Returns the “default value” for a type.
