Struct VelocityVerlet 

pub struct VelocityVerlet;

Velocity Verlet integration scheme.

Updates positions using both current and next accelerations:

q_{n+1} = q_n + v_n * dt + 0.5 * a_n * dt²
v_{n+1} = v_n + 0.5 * (a_n + a_{n+1}) * dt

Since a_{n+1} is not generally available (forces depend on positions), this implementation uses a_n for both terms, equivalent to the “Störmer-Verlet” update.

Trait Implementations

impl Integrator for VelocityVerlet

fn integrate( &self, q: &mut [Real], v: &mut [Real], f: &[Real], inv_mass: &[Real], dt: Real, )

Advance state q (positions) and v (velocities) by dt given forces f.
